I have eaten at this In N Out for years and have never gotten sick. Make sure to let them know when ordering that you have an allergy and to make sure that your meal is box separately from everyone else’s in your party. Make sure to order your burger, protein style with allergy to gluten, if you want to be extremely safe you could even say no spread and then just ask for spread packets when you get your food. I do this at all In-N-Out locations I’ve been to. All of their fountain drinks and shakes are gluten free, and because they only make french fries in their fryer by default the fryer is also gluten-free.
