Está comida que venden aquí realmente es horrible , las hamburguesas todas frias el
Queso parece que solo lo ponen en la hamburguesa todo frio , las fries duras. $50 dólares gastar en una orden para que te den comida de tan mala calidad no vale la pena.

My wife and I went to this location because we wanted a sweet treat. She ordered a small Dr Pepper float. When we received the float, it was full of ice as if they just poured ice cream on top of a regular Dr Pepper. More than half of it was ice. Egregious.

I've gone to the Sonic on S. 6th Street dozens of times and they have been so short staffed and I understand that but I just spent $40 to have my order incorrect AGAIN! It seems like every time my order has been incorrect.

The food is pretty good, but the way they’re thrown together is kind of messy. Like they did it in a hurry.
