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.

I usually buy ice from Sonic because I like the texture. I decided to buy myself dinner. Bad decision, I had to throw it away. The food tasted old and disgusting. Never again! I should have gone to Cane’s.

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

I used the drive up stall. That was novel and fun for me. The server was pleasant and said she was learning to skate to make delivery more fun. The restaurant was clean and smelled like fresh food. The restrooms were clean. That is usually a good sign of good management and training. The tots were a little cool and hard but the produce on the burger was fresh and tasty.

Edit: I spent the night in the bathroom. Something made me super sick.
Random bread triangles were gross. Service was quick and super helpful. Tater tots are delicious! Chicken strips are amazing!! There were not a lot of tater tots in my meal, there could’ve been more. Even though there was a long line, they were super quick. No Apple Pay! Card or cash only.

I come to Sonic for their drinks and this is the first time I’ve been very disappointed. Waited almost an hour for 2 drinks and a burger. My “slush” was not a slush, but instead a weird consistency and tasted very weird and sour. The nerds add on candy was melted into the drink. And the shake we ordered was clearly made a while ago and just sitting as it was melted by the time we got it. Very disappointed.
P.S. the worker brought us one straw and said she would come back with another….she never did.

Rotten and molding stawberries in my drink!! Heres the story. I got a strawberry lemonade slush and was disgusted by what I saw after the slush melted away. PICS for reference. There were rotten pieces of strawberries that had mold on them floating in my drink. If this is in their drinks I can only imagine how they prep and cook their food.

I stated three times to customize my order and instructions weren’t followed. This is my first time going to this Sonic and now it will be my last. The staff do not pay attention. The staff do not follow instructions. I like Sonic but I will not go to this one. Honestly I want the Sonic closed down or hire new staff…
