Great meal! Quality ingredients! They have a dedicated fryer and Udi’s buns on hand. They clean the grill completely before cooking an order for with an allergy. Just make sure they know to mark “severe gluten allergy” in the order AND that they follow up with kitchen staff. They dropped my tater tots in the non-dedicated fryer on accident, but caught it before it even got to me. (As with any restaurant, they just need to know your needs).
