    Ordered a breakfast sandwich and the eggs were completely burnt and cold. Bacon was more like bacon bits crumbled on sandwich. Got the bottom of the barrel bacon. Cold tots. When fresh and made with love can change a day. Instantly threw it away unfortunately 😪

    This by far the worst Sonic I have ever been to. I decided to give this location yet another chance and again the person at the window taking the order was rude, she was bothered because I took her away from her talk with her friends. I gave her my order 3 times and she still didn’t get it right and the drink was horrible. If could leave a minus 1 I would.

    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
