They do have a separate gluten free fryer they will make your fries in upon request! However, the burgers are cooked on the same grill that the buns are toasted on and it is not a large space at all. There is very likely contamination happening with the burgers (I didn’t end up ordering one after seeing the grill). Previous review mentioned a separate toaster for gluten free buns but the staff didn’t mention it to me (may still be an option and staff training could vary).
