After being asked if reasonable measures were taken to avoid cross contamination, the waiter kindly let me know that all food (gluten free or otherwise) was cooked using the same utensils/grills/no separation so not safe for coeliacs. He said that no one hadn't got sick so far by eating there but I appreciate the honesty on the cooking methods. My rating reflects the fact that it is unsafe for coeliacs, nothing else.
No
