Cruise on over to us at 3880 Gattis School Road for the ultimate SONIC experience!
The service is terrible The workers never want to work I had to go through the front door and I saw the place inside And it is super dirty The food is handled without any other person in fact I did not take my order I just left it and lost my money I do not recommend going to the place In fact to any other Sonic

Slowest sonic ever. Not even for cooked food, for ice cream. Do better.

I don’t know who spoke to me but there we’re so rude! And super aggressive when I was confused about a combo. And they got my order wrong but I just was so over it. I don’t know who’s running that location but they’re doing awful.

DO NOT GO TO THIS SONIC!!!
We got to sonic in the “mobile” lane and it said my order was supposed to be ready by 8:17. We waited until 8:50.
The car beside us already left from waiting for their food so long.
I ended up having to knock on the door and turns out my food had BEEN ready but no one took it out. When we got our food, it was cold, our drinks were watered down, and one of the corn dogs we ordered had batter still on it.

I am so fed up with this sonic location. I am done with it. I will never be ordering from here again. I have now ordered DoorDash from this location three different days at various times, and every time I order my Sonic blast, it does not show up. The reason Sonic gives is that "they ran out of ice cream." I find it very convenient that every time I have ordered, they have "run out of ice cream." I simply think it is due to them not wanting to make the ice cream, or they clean the ice cream machine before it closes. They also mess up my food order every time. Nothing is ever right. Not to mention Sonic has become super expensive, so I expect my order to come out right, and it is always wrong or missing.
