All burgers are cooked on a dedicated grill so no gluten touches them, all the fries are in dedicated fryers and the staff are very knowledgeable. The Grilled toppings aren't coeliac safe as they're done on the same grill as the buns, but the staff warned us of this when we ordered.
No GF bread or buns are available but the burgers can be served either in a bowl or Lettuce wrapped.
