They provided me with a list of food items from the buffet that are gluten free. I am celiac, but my symptoms are not "common". I can't say for sure it's safe for celiacs, but I didn't get bloated or have any headaches after eating there.
There are several food options for each meal.
The staff is all very friendly. If you see a show, your tickets get you, buy one, get one 1/2 off.
