This Braum's is one of my favorite places to eat. They have a dedicated fryer for their French fries. I also have ordered burgers with no bun and frozen yogurt in a cone. I have never gotten sick, and I go there multiple times a week!
They have groceries, including fresh and frozen items with lots of glutino products. They will make a burger without the bun (fries are not safe), and most ice creams are gf - without obvious ingredients.
