I have eaten here several times and I have never had a gluten exposure. As far as I know and what has been explained to me is allergy burgers are made on a separate grill, usually not in use and clean. I watch them like a hawk when I order food because I’m usually ordering with non-allergy burgers and this has always been my experience. I am really sensitive and this is one of the few places I feel safe dining at. Dedicated fryer for gluten free fries is a nice added bonus.
