They have very little knowledge of their gluten free menu options; I have celiac disease, and I was very open about this when ordering my food. They brought out my burger and the bun looked eerily similar to everyone else's; I questioned it and was reassured by the waitress that it was a gluten free bun. It wasn't. I was sick for days afterward.
The manager assured me that they would train their staff to prevent this from happening again, but once I get sick like this, I don't give the place another chance.
