Made my sister feel terrible for being coeliac; I hate people with an intolerance were the exact words from the staff member s mouth before explaining what could be made gluten free as if we were causing hassle.... being coeliac is not a choice, and it would be great if staff could take it more seriously & not be dismissive of it as she could be really sick if she ate something not gluten free. Would they have said the same to someone vegetarian or requesting a halal option?
Maybe just make a separate gluten free menu if the staff can t be bothered to explain what options can be made gluten free as it will save all parties the bother. I always highly recommend the food, buzz & customer service here which is why we came - but now I d think twice after this today; quite rude & disappointing
