Say hello to...eating gf in thailand: tip #1.

Tip #1: Become familiar with Thai ingredients. If you're not already familiar with Thai ingredients, than research recipes online before going on your trip. Find out which recipes use soy sauce and oyster sauce (both of which contain wheat flour). Quiet a few Thai dishes are naturally gluten-free, however most stir-fry's use soy sauce and/or oyster sauce. Traditional Pad Thai dishes don't use soy sauce, however some restaurants add it to make it more foreign friendly. Always ask the waitress/waiter if their Pad Thai contains soy sauce. If yes, simply ask them to leave it out. They can substitute it with their usual Pad Thai ingredients of palm sugar and fish sauce (both are gluten-free).
