I have Celiac and know my way around many Disney menus if you have a question about a specific place. I will say that a chef from every TS/QS will speak with you and tell you what you can/can not eat on their standard menu, and most places will make you a GF version of an item that would normally have gluten in it. I never have any trouble eating at Disney and never feel deprived. It's extremely accommodating to all allergies/preferences, in my experience.
