Review of In-N-Out Burger

I have Celiac and In N Out is always a safe bet.The only ingredient that contains gluten is the buns, and they handle these in a dedicated area. When you order, make sure to tell them you have a gluten allergy and they'll mark your order with an allergy label, then they'll keep it away from gluten including using fresh gloves and everything.

Celiac friendly?

Yes
