I got take-out here and got the massamen curry, pineapple curry, coconut soup and mixed vegetable dish, asked for it all gluten free and had no problem with glutening at all. The vegetables lack oyster sauce which is usually the main flavor of the dish, but it was still great!
If you specify GF, they will accommodate. The curries were very good.
My family came with gluten/dairy and soy allergies. The initial waiter brought a well-spoken waitress who was very knowledgeable. We had delicious GF/SF pad Thai, various curries with meats and mixed seafood, summer rolls, and green papaya salad. We are very sensitive and no one got sick.
