I went on the chain website and saw they advertise that a gluten free bun is available. You can get a butter burger or grilled chicken. I ordered a burger with gluten free bun . The person who took my order asked if I had a gluten allergy and noted it on the receipt. She told me they change gloves and have a protocol. My burger came out on a separate tray with a steamed prepackaged bun. It was excellent! I had no problems.
