I don't mind waiting in a long line for drive-thru but it's difficult when they give me the wrong order and I have to go in. Then I I have to ask if there is a difference so they can refund me. I ordered grilled ham and cheese on GF bun. The GF bun was amazing. The two slices of super thin ham and a slice of melted American in the middle not so. The drive thru operator didn't even ask if I wanted lettuce, tomatoes or even mayo on it. I foolishly assumed it would come with it. No ketchup even. I took a chance on the fries being GF though I know they don't have a dedicated fryer. Didn't get sick at least.
Not many fast food places offer gluten free bread for their sandwiches, but this one does!
