Update: When I ate here, my server told me her mom has celiac and she seemed very informed. She even said they had a staff meeting to discuss allergies and had a dedicated space on the grill and separate fryers. However, others have been told that is not true!! They do offer gluten free buns or lettuce wrapped burgers. They didn’t know which meats were gluten free for the tacos, but they were very helpful with reading me all the ingredients.
Edmond location does not have a dedicated fryer, per the manager. Brought my husband (not celiac) his burger on a regular bun. The lemonade is good though.
