MIRU
미루성수 Miru Seongsu Seongsu is the neighbourhood; Miru is the house name, also given to its signature bowl, the Mirudon — none of the posts says what the word itself means.
Compiled from 13 blog posts read in fullSources →
Miru Seongsu is a kaisendon counter on the second floor of a building in the Yeonmujang-gil alleys, near exit 4 of Seongsu station. The centre of the menu is the Mirudon, minced bluefin tuna piled on rice: 13,500 won plain, around 20,000 won with sea urchin or salmon roe, and 19,000 to 29,000 won as a set with fried shrimp and a small hamburg steak. The house finish is sea-bream broth poured over the last third of the bowl, ochazuke-style; ten posts describe eating it that way. We read 30 posts dated 29 May to 1 October 2026; 14 record an actual meal. Of the other sixteen, twelve are sponsored pieces describing dishes this place does not serve and four are multi-restaurant lists.

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.
What sets it apart
- Three posts walked from exit 4 of Seongsu station, giving about five minutes and about three minutes.
- You can book. Five posts either booked or say booking is possible, via Naver booking or CatchTable. One writer saw many walk-ins turned away that day; another notes a Naver-booking coupon for extra sea urchin.
- It is not counter-only. Three posts describe both counter seats and tables, one counting six or seven tables plus the counter. Counter seats face either the open kitchen or the window onto the alley.
- Four posts mention watching the cooking from an open kitchen in the middle of the room.
4 more
- Three posts say you order by scanning a QR code on the table.
- Three posts call the prices fair. An office worker who compared it with two nearby seafood-bowl places set the 13,500-won Mirudon against a 20,000-won base bowl elsewhere and called it more than 20% cheaper.
- Three posts found the fried shrimp that comes with the set crisp.
- Four posts went with friends, two with a mother or sister, one as a couple. None records eating alone.

Where it is
We could not find this shop’s own listing on Naver Map, so the link searches for its Korean name around this spot instead.
From the station
Three posts walked from exit 4 of Seongsu station, giving about five minutes and about three minutes.
Getting inside
| Second floor | 5 of 13 posts |
|---|
The restaurant is upstairs. Five posts describe climbing to the second floor, and one calls the stairs a little steep. Writers also mention finding it by a standing sign at the alley entrance.
The way up is only ever described as stairs. No post mentions a lift, an entrance step, or a wheelchair or pushchair — that means nobody wrote about it, not that there is none.
No one described the toilet. One post's info box says it is inside the restaurant, but that is copied information and we did not count it.
No one mentioned: In a basement · Lift to the floor · 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.

Posts that followed a TV spot
Of the 29 posts we gathered, 16 went up on a single day right after a TV spot and show no sign of a visit. They retell the broadcast, so we left them out of the counts.

We do not discard them. That a TV spot produced a burst of posts is itself something worth knowing about a place, and a star rating will not show it.

What we do not know
- Opinions on size split one to one: one writer found it small, another roomier than expected.
- No post reports queuing. One walk-in was seated at the window counter straight away and a weekday-evening booking found it uncrowded, but another writer saw many walk-ins turned away.
- Opening hours appear in seven posts, all copied from listings. All seven give 21:00 for closing; six say it opens at 11:30 and one at 11:00. Five give a 15:30-17:00 break and one 15:00-17:00; three give last orders at 20:00. No post names a closing day.
- Prices vary a little between posts. The sea urchin and salmon roe Mirudon appears at 20,500 won in a February 2026 receipt post and 22,500 won in September, but the earlier post's wording is ambiguous, so we cannot say the price rose.
- Three posts list the phone number 0507-1385-4044. Bookings were made through Naver booking and CatchTable; nobody mentions booking by phone.
- Twelve sponsored posts from late May to late June 2026 follow one template and describe dishes this place does not serve, such as bibimbap, kimchi stew and seafood risotto. We counted nothing from them, including a claim of ample parking.
