Be careful of soy sauce. I just had fried rice from a Thai restaurant. My husband went and ordered it and was very specific about them not using any soy sauce or anything w/ wheat. When he brought it home, the rice was brown and I was paranoid to eat it, so I called the restaurant and asked her why it was brown. She said it was from the chili sauce. I asked her what was in the chili sauce and she said she personally read the label herself. I was very pleased. She also said next time we order, I could send my wheat-free soy sauce and they would cook my food with that. I told her how much I appreciated their cooperation. My point is, don't ever be afraid to be paranoid and check everything out very extensively. I have DH, so I don't ever want to have that terrible rash flare up again. It's just not worth it to get glutened. As far as eating Chinese food, just ask as many questions as you have to until you are satisfied that you will not be glutened or cc'd.
Hope I helped, Laura
