Celiacs rejoice!
I am not able to eat gluten and it is very difficult to safely dine out or enjoy fast food.
Thankfully, In N Outs simple menu and well trained staff mitigate most of this peril. After years of dining almost exclusively at home, I now have a reliable go to when I am in a pinch and need a quick bite to eat. After a dozen trips, I haven't had one issue yet. Allergy orders are handled by one person, and my truck sets up high enough that I can usually spot the person who personally oversees the making of my order. They always handle my orders with such care.
The foods great, we all know that. Even people living under a rock for the last 50 years have sat in one of In N Out's notoriously epic drive thru lines for 20 minutes just to get their mouths around one of their amazing burgers.
