Sushi Yume
스시유메 Yume is the Japanese word for 'dream', so the name reads as 'Sushi Dream'.
Compiled from 9 blog posts read in fullSources →
A tuna-and-salmon Japanese restaurant on the second floor of 44-7 Seoulsup 2-gil. In the evening people come for aged tuna and salmon sashimi; at lunch there are one-bowl dishes such as a 14,900-won tuna sushi set, 16,900-won eel rice and 15,900-won poke. A 1.5-portion tuna sashimi plate was 57,000 won in October 2025. We read 11 posts from November 2024 to July 2026; one was a same-named restaurant in Yangsan and was set aside. The other 10 are all first-hand visits, dated September 2025 to July 2026. Two posts describe the place as newly opened, so it appears to have opened in autumn 2025.

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
- Four posts ate watching the chef work the tuna at the counter. One mentions watching a tuna being broken down; another sat at the counter while the chef sliced and placed the tuna one piece at a time.
- It is not counter-only. Three posts describe both counter seats and tables, two mention private rooms, and three mention window seats.
- Of six posts that dealt with price, four called it cheap and none called it expensive; one said it was inexpensive by Seongsu standards. The post that had the 14,900-won lunch tuna sushi noted the tuna was frozen and not top grade.
- Four posts said portions were big: the 1.5-portion tuna plate, a 1.5-portion salmon plate that fed four, generous eel on the eel rice, and a hearty fish-roe rice at lunch.

- Two posts ordered from a device at the table, one calling it a tablet and the other a kiosk.

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.

Getting inside

Four posts said it is upstairs on the second floor. One said you take the stairs and it is right there; another said it is easy to miss from the street. Two posts put it a five-minute walk from Exit 5 of Seoul Forest Station.
One post mentions climbing stairs to the second floor, but no one said whether there is a lift, a step at the door, or whether a wheelchair or stroller can get in. That means unknown, not absent.
Only one post mentioned the toilet, saying it is just outside the door. Nobody said whether it is separated by gender or how big it is.
No one mentioned: In a basement · Lift to the 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.

What we do not know
- No post mentions waiting for a table; one booked ahead. That means nobody wrote about it, not that there is never a queue. One post said the tuna arrived well after the salmon.
- Two posts went with friends, one with a group of four and one with a colleague. None went with family or children.
- Opening hours appear in three posts, all copied from listings, and they disagree. Two October 2025 posts give 11:00-23:00 with a 15:00-17:00 break and last order at 22:00, one adding Tuesdays off. A January 2026 post gives an 11:30 opening and Sundays off. We cannot tell whether the hours changed or were copied wrongly.
- Two posts copied the same phone number, 070-5222-4223. One post booked ahead but did not say how.
