게온 Geon Ge is the Korean word for crab; the posts do not explain the rest of the name.
Compiled from 9 blog posts read in fullSources →
A soy-marinated crab restaurant in a half-basement on a Seogyo-dong side street near Hongik University Station. The soy crab set and the spicy crab set are 34,000 won per person and arrive as one spread with rice, steamed egg, doenjang stew, corn cheese and side dishes. We read 9 posts dated 20 September to 24 October 2026; all 9 went and ate a set. One post gives the opening date as 13 September, so every post falls within its first six weeks.

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
- Six posts said the soy crab was not salty; none said it was. Two said there was no fishy smell.
- Five posts described the seating. Two said there are about three four-person tables in an inner room behind the front hall; one counted about seven four-person tables. Views on size differ: one post called it fairly roomy, two said it was smaller than expected but had more seats inside.
- Two posts said the owner brought homemade pumpkin rice punch on the house; another post bought it separately for 3,000 won.

One post said there is no dedicated parking and suggested a nearby public lot. Three other posts list 'no parking' copied from the shop's listing, which we did not count.

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
3 posts say it is walkable from the station.
Getting inside
| In a basement | 2 of 9 posts |
|---|---|
| Toilet inside | 2 of 9 posts |
The restaurant is below street level. One post said you go down the stairs and turn left; another said the half-basement entrance can be confusing the first time.
No post said whether there is a step at the entrance, whether a wheelchair or stroller can get in, or whether there is a lift. That means nobody wrote about it, not that the answer is no. One post mentioned walking down stairs.
Two posts said the toilet is inside the restaurant. None said whether it is separated by gender.
No one mentioned: Second floor · 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
- Three posts described the walk from the station, with different figures: three minutes from Hongik University Station, near Exit 7, and seven to eight minutes.
- Only one post wrote about waiting: it got in without a wait on a weekday evening. No one wrote about weekends or lunch. One post said there are chairs for waiting outside.
- Only one post said who they went with (a girlfriend). None said they went with family, friends or alone.
- Seven posts gave the same opening hours, 11:00 to 22:00 every day, and six gave last order at 21:00, mostly copied from the shop's listing. Only one post (20 September 2026) mentioned a 15:00–16:00 break.
- Four posts gave the set price as 34,000 won per person; no one gave prices for the crab stew or beef tartare. Two sets come to 68,000 won, and two posts mentioned an 8,000-won coupon when booking through Naver.
- Three posts gave the same phone number, 0507-1399-9606. Two said you can book through Naver.
- All 9 posts appeared within five weeks and repeat the same side-dish list, the 'not salty' line and the pumpkin punch in the same order. One discloses sponsorship, one says the meal was provided, and seven say nothing. Read them as possibly commissioned opening promotion.
