I return t this thread plugging 宫保鸡丁. You can get all over world, but in China, it might or might not be better. Recently, I've had it at Grandma's (Y26), Sichuan Citizen (Y58), and a place near my office (Y20).

Grandma's is actually better than Sichuan Citizen when they are on the top of their game (i.e. don't go there too close to 9p).Sichuan Citizen is a much better dating place. The place near my office (and similar) should be ruled out of this calculus unless you happen to be in the area.
