    Not ordering from here any more. Every time I've ordered delivery in the last two months, the driver is "making another stop along the way". Food has always arrived cold. Burgers, fries, rings, mozzarella sticks, doesn't make any difference, it's all cold. $$ for delivery fees and taxes. Add even a 10% tip for the driver, and your bill has increased by around 33% of the original price. Don't waste your money for cold food. If youre dying for Sonic, then drive there and eat in the car. Otherwise, go somewhere else.

    Food was super bland and very expensive we had not been to sonic in a few years so wanted to try it out prices went up but quality went down.

    I'm so disappointed with my experience last night.First of all it took 15 minutes to even order my food thru the drive thru.Then I waited at the window for another 15 minutes to receive my food.The sonic smash burger tasted awful!One bite is all I could eat I threw the rest away.I will never visit any Sonic locations ever again!! Plus the food is overpriced!

    Don’t come here if you have cash, 100 dollar bills especially, there’s a line going around the place but they could only come up with 50 dollars if you tell them to get a ten dollar tip to do it. I don’t know how a business that’s been there for 20+ years don’t have 50 dollars in their drawer
