I don't really have anything to complain about this restaurant. The food is decent, service is fast despite the lineups and the inside is clean.
I think it's one of the few Korean restaurants that Korean people still choose to go since other places have turned to suit the tastebuds of big demographics (aka non-Koreans); meaning many of the dishes are no longer authentic - they are way too sweet, not spicy, the broths taste like pure MSG.
That being said, not all dishes taste great. Pick the ones that are recommended, popular or what Korean people order.
