Gluten free - not gluten free

I am very disappointed in the Tasha’s in Mandela Square. My friend is very allergic to gluten and after confirming with the waitress 2 times prior to ordering and twice after the food arrived that the bread was indeed gluten free, my friend has had an allergic reaction after the meal. This is very disappointing since we chose Tasha’s due to the fact that they offer gluten free options. Please do not advertise something as gluten free if it is not. Tried to contact both branch and main office, but no response to the complaint.
