The staff is good about going to the kitchen and finding out what is safe and what is not. I always have good luck with the cheeseburger and a gluten-free bun. I typically get the kettle chips because they come out of a bag. I dip my burger in ranch and that is also gluten-free here.
The southwest chicken nachos are also safe. The chips come out of a bag, the queso is gluten-free and the chicken seasoning is gluten-free. The beef seasoned nacho meat is NOT gluten-free so stay away from that.
