- JOJenn OJan 4, 20265.0Food was delicious, came out quick, server was super friendly! Only complaint is we were traveling from out of state, and there are NO public bathrooms. Even though I could clearly see the bathroom. We were told it was for employees only. You mean to tell me we spend almost $50 in food and sit there and eat it and we can't even go pee? You shouldn't serve food if you can't provide a bathroom and it clearly was for the public at one time since its located on the outside and every other sonic I know gives you the key upon request for use.
- DLDrew LernerJan 3, 20265.0Fast fresh and friendly way better than the local sonic by me. Truck driver d love ring at Lowe’s across the street made it easy to grab lunch
- RWRebecca WoodDec 31, 20252.0Upper management forces employees to use products that have spoiled. I have gotten GRAY LEMONS in my tea several times. I have reported the situation several times and nobody from sonic will return my call. It's almost like they dont care....hmm. I have filled out at least 2 surveys about this issue. I have asked for phone calls from Sonic and no call. Today 12/3 it happened again. Obviously, nothing has been said to the employees.
- KCKelli CartwrightDec 16, 20251.0If you are a DoorDasher avoid this place at all costs they do not care about your delivery my boyfriend was doing a delivery and I was in the car with him and they refused to help him and made him wait in the drive thru line for over 10 minutes without any help other than telling him we would have to wait. DoorDash cancelled the order and also marked the sonic as unhelpful limiting the orders they would get from DoorDash
- SSStormDec 14, 20251.0If you are a doordasher avoid this location at all costs they do not care about doordashers they do not care about your completion rate they do not care if you don't make money by sitting there waiting they want you to wait 10 minutes in the Drive-Thru and still be ignoring you and then they get mad when you ask them again if you can get help on the order you are there for then they threaten to block you from all sonic locations
