Sushiseo is a sushi omakase counter in Gojan-dong, Ansan, on the ground floor of a building in the lane behind the NC department store. There is no à la carte: it sells courses only — ₩50,000 for the omakase, ₩35,000 for the shorter one, the same price at lunch and dinner. The chef hands each piece across an L-shaped counter; there are tables behind. Booking is required. It opened in May 2026, and the twenty-nine posts we read cover its first four months, 23 May to 14 September 2026.

The basics

When it opens

Of 14 posts: 13 wrote 11:30–22:00, 3 wrote Sunday 11:30–14:30.

Counted from what bloggers wrote in their posts; we did not confirm it with the restaurant. Where the values differ, it may be a change over time rather than a disagreement, so we show when each one was written.

These hours are counted from the posts we read. Shops change them without notice — check Naver Place before you go. Place — check hours

What people order

The most ordered dish is danhobak truffle soup (차가운 단호박 트러플 스프) — 22 of 29 posts.

The prices here are what bloggers wrote down in their posts, and they may have changed since. Check Naver Place for the current menu and prices. This list is not a menu board — it counts what bloggers actually ordered and ate. Check on Naver Place

What to order

• 차가운 단호박 트러플 스프22 ate it
  danhobak truffle soup

  The first thing on the course — **served chilled in summer**, as four posts note

  **Twenty-two ate it, and it divides them more than anything else here.** Twelve say the truffle opens the appetite; **four do not like truffle and passed it on after a bite** — one says outright that people will split on it, another finished his girlfriend's. **The cold divides them too**: three welcome it in summer, one would have preferred it warm by the end

• 광어 세비체와 바질 연어21 ate it
  gwang-eo ceviche, baji yeon-eo

  Two slices: flounder dressed ceviche-style, and salmon brushed with basil sauce and touched with the torch

  Twenty-one ate it. **Which fish gets the ceviche flips between posts** — sixteen say the flounder, one says the salmon. Three who do not usually like salmon were won over by the basil. Two found the texture soft or a little dry

• 따뜻한 면 (고토우동·이나니와우동)20 ate it
  udon

  The course's proper meal, and **the noodles are very thin** — four posts call it Goto udon from Nagasaki, two call it Inaniwa, four say it eats like warm buckwheat. Five were told to stir wasabi into the broth

  **Twenty ate it, and it draws the steadiest praise of anything here.** A chew they had not met before; a wish to know where the noodles come from; a promise to come back if they ever sold the noodles alone; a half-asked question about refills — **three call it the best thing they ate.** **One disagrees**, preferring a thicker noodle

• 오마카세 코스19 ate it
  omakase₩50,000

  The house course, **₩50,000 at lunch and dinner alike**, running to about eighteen servings: a chilled pumpkin-truffle soup, two sashimi, steamed abalone, eleven pieces of sushi, a thick roll, prawn tempura, noodles and orange. **Served only at the counter**

  **Nineteen posts ate this course.** Fourteen quote the price and every one says ₩50,000, unchanged from May to September 2026. The count of servings varies: about fifteen, eighteen, or three appetisers plus eleven sushi. **One post calls it expensive, ten call it cheap.** Six leave full — but **two say it is not enough**, both adding that a big eater would want more

• 전복찜과 내장소스19 ate it
  jeonbok jjim, naejang sauce

  Steamed abalone to dip in its own liver sauce, and then **rice to stir into what is left** — twelve posts record being told to do exactly that

  Nineteen ate it; nine call the sauce rich and nutty. **Three find it salty**, and two of those add that the rice brought it right. One thought the abalone was sliced too thin

• 북해도 가리비 관자와 우니19 ate it
  gwanja, uni

  Seared scallop with sea urchin, wrapped in nori — **the chef puts it straight into your hand and tells you to eat it now**

  Nineteen ate it and **four name it the best thing they had.** What they keep returning to is the nori: three single it out, one wanting to ask where it comes from, another naming its chewiness as the trick. One is glad the sea urchin is not piled high; another wishes it were

• 후토마끼18 ate it
  futomaki

  The thick roll that closes the sushi: prawn tempura, lean tuna, egg and spring onion

  Eighteen ate it, and **they contradict each other flatly on its size**: four found it too big to eat in one bite, one of them laughing across the counter at it, while **one thought it no bigger than an ordinary gimbap and said so with regret.** Three credit the spring onion with cutting the richness. **Four bother to record who got the end piece.** One, who had mentioned a birthday when booking, was given five

• 랍스터 새우와 대게 내장17 ate it
  lobster saeu, daege naejang

  Langoustine brushed with snow-crab liver sauce and seared

  Seventeen ate it; five are surprised by how soft the prawn is, or by the contrast of soft outside and springy in. Two feared the crab liver would taste of the sea and it did not. Two complaints: one got a prawn half the size of her companion's, and one, served too far ahead, ate it dried out

• 안키모 (아귀간)17 ate it
  ankimo

  Monkfish liver, wrapped in nori and handed to you; one post found salted pollack roe in it too

  **Seventeen ate it, and six name it the best thing on the course — more than any other piece.** What they agree on is the quantity: four remark that a bargain course does not stint here, and one rates it above a much dearer one in Seoul. **One dissents**: with the rice already seasoned, that much liver made it salty, and the rice felt like an afterthought. One found it cold from the fridge

• 구운 아나고 (바다장어)17 ate it
  gu-un anago

  Sea eel, seared and finished with sea salt rather than the usual sweet glaze

  Seventeen ate it; five praise its softness or the way the salt leaves the eel itself audible. **Two who do not normally eat eel ate this one.** Two go the other way — they like eel for its sauce and did not know what to make of this. One scraped the salt off first

• 새우튀김과 와사비 소스17 ate it
  saeu twigim

  Prawn tempura straight from the fryer with a wasabi sauce; four posts mention mashed potato beside it. One notes: one prawn each

  Seventeen ate it; four like it fresh from the oil. **Two find it heavy** — one blames the batter, one the mashed potato beside it. On the wasabi sauce they split too: two think it lifts the prawn, one thinks it does not belong, and one was told to go easy because it is hot

• 잿방어16 ate it
  jetbang-eo

  Amberjack, the summer one — three posts record being told so

  Sixteen ate it; five praise its oiliness or its chew. **One alone found it slightly fishy**, and says so as a matter of personal taste. For one writer this is the point where everything started tasting only of salt

• 다시마 숙성 참돔14 ate it
  dasima sukseong chamdom

  Sea bream, aged wrapped in kelp

  Fourteen ate it; four remark on the depth the kelp gives. One found shiso inside and thought its perilla-like scent would divide people. One calls it simply unremarkable

• 간장에 절인 참치 속살12 ate it
  ganjang akami

  Lean tuna marinated in soy; some posts call it the medium belly instead

  Twelve ate it. **One calls it the best thing she had all evening**, as good as belly tuna in Japan; **another wanted it left longer in the soy.** One notes a thread of sinew behind the salt and the sourness

• 연어 그라브락스11 ate it
  yeon-eo gravlax

  Salmon cured with brandy or whisky and spices, then lightly seared

  Eleven ate it, and four say the same thing in different words: it is not the same as salmon merely torched. Whether the cure is brandy, whisky or both changes from post to post

• 참치 대뱃살 (오도로)11 ate it
  chamchi daebaetsal

  Fatty tuna belly

  Eleven ate it and six say it melts. **Three say otherwise**: one found sinew left in it, one caught a fishy note her boyfriend did not, one thought it cut too thin. Another measures it against Osaka and finds it short

• 줄무늬전갱이 (시마아지)9 ate it
  julmunui jeon-gaeng-i

  Striped jack, in season in summer; one post notes the scoring on the surface

  Nine ate it. Two like the thickness of the cut; one would spend an encore piece on it. **A writer who usually avoids jack for its small bones** found this one soft. Another liked it with ginger on top

• 캐주얼 코스5 ate it
  casual omakase₩35,000

  The shorter course. One writer was told the difference is in the number and kind of the sushi and in the detail of the work. Five posts say it is a lunch-only option

  **Five ate it.** Nine posts quote the price and all say ₩35,000 (one writes 30,000, which disagrees with the other eight and looks like a slip). One counted about twelve pieces and called it a bargain. Of those who saw both, one was glad to have taken the cheaper course; another advises a first-timer to take the ₩50,000 one

• 청어2 ate it
  cheong-eo

  A piece that appears only in two posts, both from June 2026

  **Two ate it, and it never appears in a post after June** — presumably out of season, though **no post says the shop said so.** One was glad of a fish he rarely meets; another, braced for the taste herring can have, found none of it

Sides, and what comes with it

• 제철 사시미1 ate it
  jecheol sashimi₩19,000 · ₩49,000 · ₩79,000

  A plate of sashimi you can order instead of the course — one writer was told that with a booking you may come for this alone. ₩19,000 for one, ₩49,000 for two, ₩79,000 for three

  **One person ate it** — someone who came back for the fish alone after the course, ordered the two-person plate (₩49,000) for herself, and got **eleven kinds**: fin, scallop with sea urchin, two cuts of tuna belly, steamed abalone with its liver sauce, monkfish liver, amberjack, striped jack, salmon, flounder and sea bream. **The shop says the make-up changes with what comes in that day.** Her one complaint: the tuna navel was tough

Sweet things

• 오렌지17 ate it
  orange

  The last thing: a single piece of orange

  Seventeen ate it; three appreciate that the peel is cut away for you. **One wishes there were more to the dessert** — a sorbet, say

Parking

5 posts say you can park. None say you cannot.

There is parking, but the barrier does not open by itself. Five writers actually parked, and all five tell the same story: the underground car park of the building, with a gate you have to ring the restaurant about when you arrive. One puts it plainly — it says parking available, the barrier will not lift, do not panic, just call. It is free, and two found it roomier inside than the narrow entrance suggested. But the posts disagree. One tried the ramp, got no barrier and parked on the street; two say flatly in their header blocks that there is no parking; a fourth thought the basement cramped enough to recommend the public car park nearby. The phone call looks like the difference — but no post says the shop told them so.

Who came, and with whom

Getting there

Getting inside

It is on the ground floor. One post makes that certain: she parked underground, took the lift up to the first floor and walked in. The registered address, unit 102, says the same. But no post says whether there is a lip at the street door, and none mentions steps.

Whether a wheelchair can get in, we do not know. Exactly one post says the entrance, the seating and the toilet are all wheelchair-accessible — and those three lines sit inside a block lifted whole from the shop's Naver listing, alongside the private-hire policy and the accepted payment cards. That writer did not see a wheelchair, or a threshold. In the other twenty-eight posts the words for wheelchair, pushchair, ramp, threshold and step never appear once. So we did not count it: getting this wrong sends someone on a wasted journey.

Not one writer looked at the toilet. It appears in two posts and both copied it: one as a line in a header block saying there are men's and women's toilets in the building, one inside a list of Naver listing tags. Whether it is inside the restaurant or out in the building, nobody went and saw.

No one mentioned: In a basement · Ramp at the door · Step at the entrance · Step-free access · Toilet inside · Accessible toilet · Separate restrooms. That is not the same as there being none — it means we could not confirm it. Worth calling ahead, and do tell us: we will put it here.

When the posts appeared

What we do not know

• On salt the posts contradict each other head on: six say it is too salty, three say it is fine. The complaints are vivid — one writer noticed it after the salmon, watched her sister start drinking water, and reports all three of them still drinking it at home; one found the monkfish liver salty in a single mouthful of nori; one was taken aback by the abalone sauce. The defences are just as plain: one had read about the salt and felt none of it, another who dislikes salty food found it judged exactly right. Because the sushi is brushed with soy at the counter, there is nothing to adjust at the table, and the day's seasoning is simply what you get. One writer, a trained cook, deliberately tasted the rice on its own, called it properly balanced red-vinegar rice — and allowed that on other days it may genuinely have been stronger. Two posts note that you can ask for it lighter.
• Twenty-nine posts in four months deserve some context. Three record that the shop gives a drink — soft or alcoholic — for a receipt review; one urges readers to ask for it up front, since it comes first. And one writer says she kept being served Sushiseo's advertising reels on Instagram until she booked. Not one post discloses sponsorship. Instead fourteen state explicitly that they paid, an unusually high count, and three more say someone else did — a brother, a sister, a friend. The remaining twelve say nothing, which is not proof of sponsorship, and not proof against it.
• Nobody came without a car. In twenty-nine posts there is no account of arriving by bus or subway. Two quote a distance — 998 metres, fifteen minutes on foot, from exit 2 at Jungang station — and both lifted it from the shop's Naver listing. Six say they drove. One writer put it best without meaning to: she skipped the drink because she was driving, and means to come by public transport next time and have one — which, given how much this place sells to drink, is the most useful hint here. Whether she ever did, we do not know.
• Nobody queued — with bookings only, there is nothing to queue for. What varies is how full the room was. Two found it empty: one at eight on a Wednesday with no other table in, one in late June who thought word had not got round yet. Five found it full — a weekend evening with every counter seat booked, a Thursday half past one with the bar nearly full, an eight o'clock already busy, a near-full room, and a Sunday lunch where every other slot had gone. The empty evenings fall in June and July; the full ones from July to September.
• You may bring your own bottle, for a fee. Two posts give the same corkage: ₩20,000 for whisky, ₩10,000 for anything else. One brought sake back from Sapporo, one a bottle of whisky; the first was given a tokkuri and an ice bucket to go with it. The shop's own list runs to sake, whisky, soju, beer and highballs, and two writers are cheered to find an omakase that sells soju at all. There is no draught beer — three say so and two mind.
• This place opened in May 2026, and what we read is its first four months — which means the posts catch it changing. Two July writers were startled to see the rice come out of a ziplock bag; a writer who returned at the end of August found a proper rice tub, and was told the owner had gone looking for one after customers mentioned it. The herring that two June posts ate does not appear after July. Four months of talk is worth exactly four months of trust.
• Nothing was dropped: all twenty-nine confirmed posts are about this restaurant. But twenty-nine posts are twenty-eight people — one blogger wrote twice, once for the course in May and once for the sashimi in August. Two others went twice and wrote once, returning within a week. Twenty-six posts are first visits; three are returns.
