*update June 2018*: used to be a diehard fan but it’s just not as good as it used to be! Not bad, just not my fave. They changed their buns (no more poppy seeds) but they taste great and hold together the burger better than before!! I get the Hickory Burger with the sauce. I asked and they said the Hickory sauce was gluten free. I'm extremely sensitive and had no problems! So tasty!! Another reviewer said one of the sauces was not gluten free but that was awhile ago. Be sure to ask!
