Review of In-N-Out Burger

I've never had any issues here and I've eaten here at least a dozen times. Just tell them it's an allergy order and they will prepare it separately. Note: animal style fries and burgers are never gluten free because they grill the onions on the same grill they use for the buns. Do not order animal style at any In 'n Out Burger and you'll be fine.

Celiac friendly?
