Employees either close early or the listed times are incorrect. I placed an online order just before midnight on a Friday, it was supposed to be ready at 12:05, I arrived at 12:10 and the entire restaurant was dark. They'd closed and left. I saw the an employee (the last one there I believe) walking across the street towards McDonald's.

Every time I have went to go get Sonic there is always an excuse. The grill isn’t hot enough, system is updated, closed but really open, the list goes on. This place is horrible and needs new management or something. I’ve received 1 meal from there and it took them 40 mins to make it with only me in the drive way. Will never try again to eat there.

They were super fast got my order out in less than 5 1/2 minutes after I ordered! Almost like winning the lottery , because its not often food comes out that quick, and it was all right! A small picture of my baby's slush and crinkle fry.

Went to this Sonic 2 hours before close. Was told they can’t to blasts, but can do shakes. Got a medium and small shake, large mozzarella stick and large jalapeño peppers. The shakes are literally just cups full of whip cream and a couple of toppings to make it seem like they actually did their job correctly that they are getting paid for. No joke NO ice cream in these. Sonic used to be a place to go when you want a late night snack, but it’s not worth it anymore. Not like this review or any of the negative reviews help at all because you just get a generic response to call their corporate line instead of addressing the issue and training the employees better.
