I have heard that Arby's was o.k. but I wanted to check with the store.
Dear Sara Arby's restaurants utilize CORN OIL for deep frying all of our products. The only product we sell with tree nuts--not peanuts--is the sticky bun of T.J. Cinnamon's. This product is oven cooked and never comes near the fryers. The chance of cross contamination is relatively negligible. If you have questions, please call the number below.
