I havent tried the Chinese at WDW,wanted to but I was the only one so we opted for Mexican CS.. Anyway I did try the Japanesse CS and liked it, it wasnt fantastic but it was good..
I have only eaten in China a few times and I would say that it is one of my least favorites.. If you really want Chinese food, maybe try the take out area, less expensive..or go off property....not sure if others might have fave Chinese restaurants off property. I have to tell the truth, I think the Chinese restaurant is not good.
