Hamburger was cold but the fries were hot. How is that possible 🤔 this is the 3rd time that happens the samething. Bread was a little bit hard too . I eating because i was hungry or else i wouldn't eating. Oo i ask for a MD size. Looks more like a SM size.

Nothing spectacular. Sonic used to be my favorite restaurant but this one has something different and I spent more than I wanted to. I think the hype on the hot dogs lured me in. Asked my friend if he liked the Coney... he said "Coney, what? You brought me a hot dog. What do you think?" He would have chastised me for spending as much on a hot dog. Lol. But the food is safe and good and the service is as good as can be expected. Nothing wrong. And there was no wait and there were only one or two other customers while I was there
