I've been here several times (after a few failed attempts) and each time i've gone i've been happy. The food is really good - but don't go expecting student prices. You pay for the quality. The only reasons I wouldn't go more often are:
1) they aren't open late (e.g. 2am when i'm hungry looking for cheap korean food) and
2) It's a bit expensive (e.g. 2am when i'm hungry looking for cheap korean food)
This is the kinda place you take your parents to try Korean food. It's not ghetto like where youde go (Ok, it's just slightly ghetto).
