I'm gluten free and they have a "non-gluten" bun here. It is $1.50 extra but is a delicious bun! It's actually more of a biscuit and I want to find out where they get them and if I can buy more! They taste as if they could be made in house. The burgers were good and the milkshakes take you back to a different decade. The soda fountain has very unique flavors like blueberry soda, doppelgänger and Mexican cola. All in all I recommend you give it a try.
