I have to start off by saying that I'm very picky when it comes to chinese food. Having said that I think that Wai Wai is a great chinese restaurant mainly because their ingredients are always fresh. I hate eating chinese food that tastes like its been reheated and the chicken is old. You wont get that here. I got delivery or take out from Wai Wai rather frequently and the quality was always consistent. I gave four stars because I tried a few dishes that weren't the best I've ever had but in general and especially in Pittsburgh, I think its a great chinese restaurant. Very tasty and very FRESH.
