In’n’Out is the best fast food place, especially if you have a gluten allergy! You can tell them when you order that you have a gluten allergy and they will be extra careful with your food and prepare it at a separate station. Get a protein style burger and it’s wrapped in lettuce! Also the only thing they fry is the French fries so those are safe for gluten allergies as well. Not only are they great with the allergy, the quality is top notch. Fresh and not overly greasy. My favorite! Oh yeah, the shakes are great too!
