I have Celiac Disease and have eaten at the Lees Summit location several times. I've had their Burger without a bun, their Fries, Salmon, and several of their Salads. I have not had any adverse reactions but I do think they fry their Fries with breaded things so you may want to avoid them if you're vunerable to cross contamination. The Staff hasn't been especially knowledgable so I typically talk to a Manager when I order. They don't have a ton of menu items that are GF but they do have a few options and a great Happy Hour!
