A basement bar on Donggyo-ro 255-1 in Yeonnam-dong that plays R&B and pours cocktails and whisky. We read 12 posts from January 2025 to October 2026, and all 12 describe actually drinking there. Prices written down: gin and tonic from 11,000 won, 13,000 won for the Bombay version (January 2025); tequila sunrise with an extra shot 19,000 won (September 2026); prosciutto plate 12,000 won and sausages 14,000 won (January 2026). Most posts copy hours of roughly 7:30 pm to 4 am. There are both bar seats and tables — three posts went alone and sat at the bar, three went with friends.

Rows without a count: 2 of 6 posts.
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
- Two posts actually had requests played. One found a staff member DJing by the entrance and requested the Isley Brothers' 'Between the Sheets'. A five-year regular writes that early in the night, when it is quiet, the mix leans on requests, and songs come up when they fit the flow rather than immediately. Three more posts only repeat that requests are possible; we did not count those.
- Three posts say a free snack arrives when you sit — pretzels in two, 'simple snacks' in the third. Several posts say outside food is allowed, but all copy the bar's notice; nobody wrote that they brought their own.
- Three posts say prices are not high and one says they are a little steep. Two of the three come from the same regular, who puts cocktails at 10,000 to 20,000-something won. A September 2026 post calls cocktails cheap; a January 2026 post says they are a bit pricey.
- Four posts describe the seating. Two list bar seats, tables for three or four, and group tables for six to eight; a September 2026 visitor sat at a table, then moved to the bar since they were alone. Two posts call the room large. Several mention a wall screen about 10 m long.

- Two posts describe occasional live shows from experience, both by the same regular, who says you can watch standing without a seat. A September 2026 post only heard they happen irregularly.

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
1 posts say it is walkable from the station.
Getting inside
| In a basement | 3 of 11 posts |
|---|
Three posts describe it as underground from their own visit: one nearly walked past because it is on B1 but was drawn in by incense, one says you hear R&B as you go down the stairs, and one attended an event in the basement bar. Two mention a large mirror by the stairs and a smoking spot outside the door.
No post says whether there is a step at the entrance, whether a wheelchair or stroller can get in, or whether there is a lift; one post only mentions going down stairs. That means nobody wrote about it, not that there is none.
No post says where the toilet is or whether it is split by gender. We don't know.
No one mentioned: Second floor · 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.

What we do not know
- No post mentions waiting to get in. One September 2026 post waited close to ten minutes for a cocktail and found the service a little lacking — the only post to say so.
- Only one post describes the walk itself: about ten minutes from exit 3 of Hongik University Station, on a main road and easy to find. Other posts' 7- and 10-minute figures are copied info.
- Posts mention tables for six to eight, but none describes going as a big group — one post was a speed-dating event that had rented the bar.
- Opening hours have changed, and the current schedule isn't certain. A January 2025 post gives 7 pm on Fri–Sun and 8 pm on Mon, Wed and Thu; posts from May to August 2025 give 6:30 pm–5 am on Saturday, 7:30 pm–4 am otherwise, closed Tuesdays. A January 2026 post still says closed Tuesdays; an October 2026 post copies 'daily 7:30 pm–4 am, no regular holiday'. Only one post says that, so we can't tell whether Tuesday closing has ended. All of these are copied listings.
- Five posts give the same phone number, 0507-1339-0606. Several copy that table reservations and song requests go through Instagram DM, but no post describes actually booking.
- Prices are recorded per drink, not per visit, and no post gives a whisky price by the glass or bottle. A May 2025 post from a regular says the food menu used to be longer and has shrunk a little.
- One September 2025 post says the bartenders previously worked in Apgujeong before moving to Yeonnam-dong; that is hearsay and not counted. No post mentions the bar moving from this address.
- One September 2025 post adds boilerplate copy about signature and seasonal cocktails after a short visit paragraph; we treated that part as copied and did not rely on it. The September 2026 speed-dating post discloses sponsorship by the event organizer, not the bar.
