We eat here every time we pass through Lancaster - two or three times a month. We have yet to get sick here and have only ever gotten sick once at an In-N-Out, which is impressive since it’s the only place my DH trusts when traveling. We feel so comfortable in their assembly line set up that we don’t feel the need go into the celiac spiel at time of ordering. DH gets the Flying Dutchman (two patties with cheese in the middle). Their website lists the allergen website for their other products. Well worth it for the peace of mind.
