    Big shoutout the the guy running the place during lunch hours. He always has an excellent attitude and exemplary customer service. Give that man a raise.

    Service was decent but the portions are laughable for the prices. Two “burgers” are now the size of one for more. Im done with fast food. It is now too expensive and crap. Oh wait it’s always been crap just not expensive crap

    The guy at the counter was so sweet! He said the snickerdoodle frosty was discontinued but still made it for us with different ingredients! He also gave my daughter a cup when he didn’t have to. Another thing he did was give her a little toy that was sitting there on the counter. Overall great experience!

Huge black mushy spots.. I'm just glad I noticed it before I even took one bite, otherwise I would have definitely..you know what..
