We live very close, so we eat there often. My son and I both have celiac. We always get burgers with the GF bun, and never had any issues with getting sick. Only wish they had a dedicated fryer, so we could have fries.
We decided to try this restaurant after hearing they had gluten free buns. The kids taking orders at the counter were very nice and helpful but knew nothing about gluten. They let me read the ingredients in the bbq sauce which I deemed safe. They do not have a dedicated fryer so I opted for a bbq bacon cheeseburger with a bottle of water. I noticed they toast the buns so asked for it to not be toasted to avoid CC. Despite all that, I got very very sick. If you’re not celiac the burger was absolutely delicious and the bun so soft. Don’t recommend for celiacs, sadly.
