Loads of things on the menu are marked as gf. My daughter is coeliac and very sensitive almost immediately- there were no ill effects at all so I think this place is safe! We had chicken wings and loaded fries. Staff were also lovely. A good spot if you are near the Royal Mile.
The waitress knew exactly what we could and couldn't eat, and even gave us extra gluten free food bc some of what we ordered (on the platter) wasn't. Everything was clearly labeled on the menu, although almost all of the meats (and sauces) are gf, even if those aren't labeled on the menu. Would highly recommend this place
