There are many gluten free options on the menu, including gluten free buns, but the waitress did not seem to understand what I was asking about cross-contamination. I got sick shortly after eating a "gluten-free" sandwich here.
I had a gluten free turkey burger, they have gluten free buns. Which are better than most stale, store bought gluten free buns! I also had home made french fries, which were fantastic. I didn't ask if they have a separate fryer, but I didn't experience any gluten symptoms. I will definitely be back!
