I have celiac and am very sensitive. They have gluten free fries (dedicates fryer for fries), and they have a dedicated grill for burgers separate from where they put their buns. The fries are really good. I don’t eat out a lot since I have gotten celiac, so the grease made me feel a little blah, but I had no reaction with gluten. They are very aware of celiac too, which makes it even better.
