    Horrible service. Wait times are 10 times longer than any other sonic around. I’m seriously wondering if there’s a manager on site cuz no worker looks like they want to be there. Been like this every visit that I just had to write a review at this point.

    WORST FOOD IVE EVER BEEN SERVED IN MY LIFE!! Let's begin. So my wife and I pull into the drive thru and tell the guy its our first time at sonic, if he had any good suggestions and he tells us to go pull in to where the vehicles park and to pull forward. Tell him theres no one behind us and didnt offer any help what so ever. So after a minute of looking at stuff we get 2 double smasher cheeseburger combo and I ask him if I can get fresh fries and the dude had no idea what I was talking about. Kept arguing with me that they have groovy fries and their fresh. So we pull up, charge was freaking 27.99 for 2 basic combos. I had 2 dollars in quarters and guy tells me Sonic doesnt value the quarter after a dollars worth so they can only except 1$ in quarters and thats it and than asks if I want my money back to leave. I said ive never heard of that but ok whatever and gave him another $20 bill. Remember its our first time at a sonic and this is our experience so far. So now comes the worst part. The food was absolutely disgusting. Fries were so hard you couldn't even squeeze them and if you ate one it would try to get stuck in your throat because its burned to a cinder. The double cheeseburgers were burnt and dry with no flavor whatsoever. The smasher burger has meat flared out all around the burger and that meat was all rock hard and burned and cold, everything was stone cold. Only took a couple bites of the burger cause I didnt want to get sick. Swear to god I've never been so pissed off after a fast food experience in my life. I took both video and pictures which I will send to corporate when im done here. I mean look at these fries and burgers. My ticket number was 358882, drive thru number 382 if it matters. Carhop was Brandon. Stay away from this place if you value your health because the employees do not care at all.

    The past 4 times we've visited after 11pm, they stated they are no longer serving ice cream. This didn't use to be the case, as this was our go-to spot for a late night treat. I understand not serving 30 minutes to close for cleaning procedures, but to consistently stop selling after 11pm when the store doesn't close until 2am seems odd. There is no reference on the website to indicate to customers of a stop-time for selling ice cream.

    Watermelon peach refresher 😍 Cheese tots 👍 Tropical heat smasher👏 Worth the drive, just for the nostalgia of the place. Good ‘ol’ Sonic. Staff are super friendly. Only deduction of 1 star is because lines can get pretty long, dreadfully so. Nevertheless, I keep coming back!
