Agree with the above, my sil and niece are gluten free and they had no issues, it took a bit of research by my sil though.
Once we were ready to decide on a place she would check the app for GF options and suggest one or two places that had FL options for them and we would pick one of those.
I didn't pay that much attention to what they ordered but we ate QS at Rosies, woodys, the mexican quick serve in epcot, sauli canteen and regal eagle.
