Cruise on over to us at 1022 Us Hwy 281 South for the ultimate SONIC experience!
I've tried multiple times to be kind to this restaurant and give them multiple chances but this has to be the worst Sonic I have ever been to. They can't even make a peanut butter shake correctly. They left big chunks on the bottom so every time I took a sip all I got was chunks. I couldn't even finish the burger because it was just sloppily made and completely saturated with pickle juice before I could even eat it so it had obviously been sitting there for a while it just looked like globbed mayonnaise and pickles that's it so it was an unappetizing. I had ordered the slam burger 6.00 special. Mozzarella cheese sticks, and the shake. The best thing about the meal was the mozzarella sticks and that's pretty much all I ate My tater tots were cold and this isn't the first time this has happened. They either burn the stuff or they give it to you cold or it's just completely saturated and grease it's just nasty and it's such a travesty because it's one of the closest sonics that we have around.

Prettiest burger I’ve ever eaten! For once it really did look like the commercial lol . It tasted just like it should.
But they did forget my fries… good thing I got mozzarella sticks!
