I have had a super super good experience eating gluten free while in Disneyland with my family. My mom and I are both celiac so even a little gluten makes us really sick. But disney is fantastic and there is little cross contamination if you have any kind of food intolerance.
So far we've eaten:
-Carthay Circle (they had the best gluten free bread!)
-Anywhere that serves pancakes and waffles has them gluten free too.
-Big Thunder BBQ (they take off the ribs, and the sauce on the chicken)
Are there any other places with good gluten free options? A.k.a. somewhere that has something different other than replacing the bread. Or places in Downtown Disney?
