I ate at this location a couple of weeks ago. They have a dedicated fryer and were very careful not to mix my fries up with the rest of my party. Their allergen menus are available online, are interactive, and suggest alternative selections for gluten free. They assured me that I wouldn't have to worry about cross contamination on the grill either. The gluten free bun, however, was very dry and I took it off my burger. I was very impressed with how well they took care of me.
