I've had the korean bbq (2nd floor) several times now, and it's consistently good. We probably go once a month now.
Service is great, and the restaurant is very clean.
While it's not a very comprehensive korean bbq in terms of banchan (none really) and grilling selections, each item they have is top quality and delicious. Kalbi is great, the bulgogi is great, shrimp and marinated chicken is good. There's some other assorted seafood and pork as well. Then you have some kimchi/radish, lettuce for wrapping, and each person gets a bowl of white rice.
But in any case, you should fill up on the meat at korean bbq, not the banchan right? So I think overall it's pretty good :).
