FYI, their lunch break is at 3:00 - 4:30 pm.
Some seats are a little sticky but overall, the restaurant is pretty clean. Service is very traditional Chinese so you do have to get the server's attention for service. The restaurant is often filled with a lot of International Chinese Students which I assume means the dishes taste pretty authentic.
I've tried the Xiao Long Bao (Soup Dumplings), Kung Pao Chicken, Szechuan Chicken, Sweet & Sour Chicken, and Eggplant Stir Fry with Minced Pork. All were pretty good, but I hope you like the taste of black vinegar.
I definitely plan on coming back and exploring more of their menu!
