Dedicated gluten-free fryer. The waitress was very helpful and attentive to making sure that our food was prepared free of our allergens. The burger was delicious, and the gluten-free bun was really tasty. Hard to say whether cross-contamination was an issue, as I was traveling and could have reacted to food I had gotten elsewhere. I have non-celiac gluten sensitivity. They do list on their menu that the kitchen is not celiac-friendly.
