This place is famous for its wonton soup but I personally go here for the seeju gnow haw (no idea how to say it in english). Very tasty with the right amount of garlic and black bean.
I wouldn't say the place is clean but it's not particularly dirty given that it is Chinatown. Service is good and the waiters speak Engrish.
Overall I would say that the food is average with a few above average dishes. Reasonably priced as well. The clientele can get obnoxious at times given that the restaurant is open so late and as such I prefer to go earlier.
