Whittles offers a gluten friendly menu. They have a separate menu offering burgers and sandwiches on gluten free buns/hoagie. They do state that they cannot guarantee no cross contamination as they have lots of hand breaded items in their kitchen and those with cialiac disease should caution.
I have had several items and have not had any issues. Just let the server know you are order a gluten friendly item.
Service is wonderful.
