    Legit rudest people ever working here on the night shift. Won't be going back to sonic, also be prepared to wait for at least half an hour to eat cold food.

    Asked for and got charged for a cheesecake master shake , instead I got a regular vanilla shake. Check your food before leaving

    All Sonic locations are slow, but this one was notably slower, taking over 20 minutes. Way too long! We didn't receive any condiments, even the ones we had actually ordered. There was no syrup for the french toast sticks. No marinara for the mozzarella sticks. Ordered extra ketchup and mustard on one of the burgers and it was light at best. Same with the chicken sandwich. I asked for extra mayo and there was none. I had to add my own at home. Pretty terrible experience!

    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.
