Haechoseom
해초섬 Haechoseom means 'seaweed island'; a story posted in the restaurant's rooms says it is named after a small island near Joyakdo in Jangheung, South Jeolla, where seaweed grows thick.

Haechoseom is a Korean set-meal restaurant on the 10th-floor dining level of Lotte Department Store Konkuk Star City in Gwangjin-gu, Seoul. Meals are ordered per head: a base of mixed seaweeds, seaweed bibimbap and seaweed soup, topped up with grilled fish, bone-in raw fish and boiled pork. Prices run from 16,000 won (Haechoseom set) to 27,000 won (Bada set) and 35,000 won (Myeongpum set) per person. We read 30 posts dated 6 August to 15 October 2026; nine describe actually eating here, and the rest are about other shops in the same department store or are new-listing roundups.

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
- There are private rooms: eight of the nine visit posts mention them. One put the number at two or three, another at exactly three, and one said they range from a small room for four to a large one for ten or more. Two posts booked a room, and one family lights candles on a cake and sings happy birthday in theirs.
- Being on the 10th floor, it has a view: six posts described looking out over the Konkuk University area from a window seat or room, one naming the university and its hospital, another the campus lake. One post said only one of the three rooms (room 3) has a view, and booked it for that reason. Another got a window table only by arriving before 11:30 on a weekday.
- Expect a wait at mealtimes: three posts saw people queuing — on a Wednesday at 1:30 pm the waiting list was full of names and party sizes; on a weekday at 1 pm there was a wait but tables turned fast; and one dinner visit also had a queue. One post walked straight in before 11:30 on a weekday. Two mentioned a waiting area outside the door. No one recorded how many minutes they waited.
- Families come here: three of the nine visit posts went with family — one for every family birthday, one two or three times a year with a spouse and nine-year-old son, one feeding grilled mackerel to a 28-month-old. Two posts noted high chairs. One post went as a couple and one with a friend.

- Three posts said the seasoning is not salty — one had worried the dried croaker would be, and found it wasn't. Four noted that the bibimbap comes with a soybean-paste sauce rather than chili paste. No post called the food salty.

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.

6 posts say it is walkable from the station.

It sits on the 10th-floor dining level, and one post rode the elevator up from the subway station. No one wrote about a step at the entrance or whether a wheelchair or stroller gets in — not that there is a problem, just that nobody said.
One post noted there is no restroom inside the restaurant; you use the department store's. No other post mentioned restrooms.
No one mentioned: Second floor · Ramp at the door · Step at the entrance · Step-free access · 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 11 posts we gathered, 2 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
- Views on service are split one to one: one post found the staff friendly, while a regular who comes two or three times a year wrote that at lunchtime and other busy periods orders often get missed and you shouldn't expect much warmth.
- Seven of the nine visit posts, all from August to October 2026, follow the same outline (recommended for family gatherings and engagement meetings, private rooms, easy parking because it's in a department store, near Konkuk Univ. station) and share hashtags. Only one discloses receiving a meal voucher; the other six say nothing either way. The two posts outside this pattern come from families who return regularly.
- All the opening hours we have were copied from listing blocks: six posts give 11:00–20:30 daily, four of them adding last orders at 19:45, and one gives 10:30–21:00. The restaurant closes on the department store's regular closing days and may shut early when ingredients run out.
- Prices are from posts dated August–October 2026: per person, the Haechoseom set is 16,000 won, the squid set 17,000, the Bada set 27,000 and the Myeongpum set 35,000; the medium seafood bossam is 40,000. Two posts paid 70,000 won for the Myeongpum set for two. Three posts called the prices reasonable, one of them a post that received a free meal voucher; none called them expensive.
- The phone number 02-2218-3965 appears in four posts' listing blocks. Two posts made a reservation and two advised booking for groups or rooms, but none said whether they booked by phone or online.
