The food is good bordering on great. (Especially the pizzas, kimbap, ddokpoki, bulgolgi, and ramen.) The prices are reasonable, and the portions are usually generous. They will often bring out some fresh fruit or ice cream at the end of dinner at no charge.
Paradoxically, the atmosphere is intimate, but kind of on the loud side with the music. I don't mind too much, but be prepared to yell a little bit. That said, what really makes this place shine is the service. I usually roll in there with a crew of about 12 people every Wednesday night and the staff is SUPER patient and helpful. Also, they get the orders out quickly and never gripe about having to split the checks among so many people. (Which is why I tend to tip them about 30-40%)
Anyway, give them a try. You won't be sorry. :)
