Was pleasantly surprised to find they had GF burgers and dogs, I didn't think I'd be able to eat anything there but I was extremely happy with my food. Kept it all separate. I wasn't sure about the condiments ingredients (I am picky as I have other allergies / sensitivities) but he said the owner who is GF uses the mustard so I went with that. Also they had GF sweet potato corn chips.
Hot dogs/burgers are GF and delicious! Can also use GF marinade for grilled chicken upon request. Keeps some GF bread/rolls in supply too. Most ice cream flavors are GF too! Knowledgeable about cross contamination.
