Culver’s has the best gluten free bun ever and they heat it in a separate package for you. The have a great nutritional brochure. However, the hamburger patties are not gluten free, but they will sell you a bun. I usually get a chick fil a grilled chicken patty (their buns are terrible) and go next door to Culver’s and buy a bun for it. They are always very nice and accommodating! The brochure says they have plenty of soups and other items gluten free.
