I was worried about Buffalo Wild Wings because their website said that fryers were shared between gluten and non-gluten containing products, but my grandson wanted to go. We went to the Buffalo Wild Wings in Ankeny. Iowa. The staff was super friendly and helpful. They produced an allergy book and helped me select the chicken nachos. The waitress promised to warn the kitchen not to cross contaminate. They were HUGE and totally delicious!! I'd definitely come here again!
