I haven't had any issues with cross contamination. Each time I go here I ask for gluten free buns with my burgers and ensure the burgers themselves are gluten free too. The staff are always happy to help you choose the right burgers based off your dietary requirements. They also understand and place a coeliac note on your order which I find helpful as most places don't have much knowledge on the matter. Only issue is there isn't many fries or sides available.
