Despite the high risk of cross contamination at a busy fast-food restaurant, I have never had an issue at this location. If you tell them you have a "gluten allergy", they take excellent care of your order to keep it as safe as possible. My order always comes out a bit late, which is a good sign: it means they're taking extra care and not rushing it.
