We visited the restaurant for dinner while in Seoul in Aug 2010. It is an easy 10 minute walk from the COEX Samseong (world trade center) subway stop. Go out exit 3 and walk straight (away from the COEX) for about 7 minutes 150 meters, across the hill top side crossroad - turn right into a small street/alley just past the Mercedes Benz building, and it is almost immediately on your left (downstairs). It is a fancy place with delicious food and excellent service (I think best to make a reservation if you can). They did appear to have some menus with fish (not sure), but they had at least 3 fixed course menus that were all vegan (they speak some english, but we also used our "vegan passport" to let them know we were looking for all vegan food). We choose one of the mid-priced menus - you would certainly pay more for a meal like this in the US - courses just keep coming in waves, and just when you think it might be over, another whole set of dishes is delivered - and we tried a specifically Korean fermented beverage (sort of like beer) call "Makgeolli" and it was very good. As with so many of the Korean veggie-oriented (since probably not technically all veggie) restaurants we visited, the proprietor was very proud of the food and the place, and wanted to let us know about the dishes, etc. Overall, definitely worth going out of your way to visit this place; best meal we had in Korea.
