I have visited several times, and never had a bad experience. It is up to par with most similar burger places, where you order at the counter but it is still fast food.
My highlights that bring me here over similar burger resturants are: the lettuce wraps, lemonades, and I really love love the salt and vinager fries. I couldn't pass up these fries they are seriously yummy.
But burgers are tasty, nothing over the top amazing, nothing to really complain about either.
My daughter and boyfriend really love the frozen custard as well. ( I'm lactose intolerant of I would try it)
