A very limited number of options, but I’ve had fine experiences ordering the gf pizza and grilled chicken sandwich with gf bread. I never eat the fries though so either swap it for salad or let your companion eat the fries. With the pizza I had a very nice waiter once tell me the gluten free ones will always come in a square tin while the regular will be circular. This has made me feel much more at ease since both versions are thin and difficult to tell apart otherwise, especially in the dark. I also had herb parmesan popcorn many times without issues.
