Never had a reaction, usually get the chicken pad thai. If you ask about gluten free, they're educated about it. EDIT - Had terrible service and no one took me seriously when I asked to make note of celiac disease / prepare on separate surface. Also the food isn't good anymore, not sure if they are cheaping out on ingredients but the last couple times the food has been terrible and more expensive.
