    Horrible service. I enjoy their drinks but takes over 30min to get.

    Stopped for breakfast burritos they were very disappointing and they got our order wrong. Hardly anything in them. Save your time and go elsewhere

    Every time i come here i get treated like im bothering the workers. They are always so rude and not welcoming, i dont normally leave reviews but i am just blown away with the consistency of their attitudes not being corrected by management. I will not be coming back to this location and i recommend you dont either. I just hope management makes a change so i can just order my sonic without being treated like garbage.

    Just brought home a Jr. Dbl cheeseburger took one bite. Threw it away. Meat tasted funny, smelled bad and was horribly put together. Mustard oozing out of bun.... needless to say I will not be ordering from there ever again.
