I’ve been going to this sonic for a very very long time, but I’m so sick and tired of them not giving me the right orders. They will mess it up so much I’m always missing something in it or they don’t do the order right. Not only that I’m so tired of how these employees are some of them are not nice to the customers. I used to work there a couple of them are nice no matter what but the others need to stop giving so much attitude just cause they ain’t having a good day at the job! Don’t like it then find another one, stop giving people attitude or discriminating certain people and I’m one of those people!

I absolutely love this Sonic! It’s so close to my work that I go here two to three times a week. Kolby usually brings out my order and he is so friendly! 5 stars for sure

I've been eating food from this Sonic location between 2-4 times a month for more than 5 years now, and it really is the best Sonic in the country. I have absolutely no idea what the criteria for the actual competition is or how it's judged, but for anyone who's curious about what that looks like from the standpoint of a regular customer: The staff is always friendly and helpful, the facilities are well-maintained and clean, and when you combine those things with the way they've been actively in the local community, you get a very nice and authentic small town, drive-in vibe. The ingredients are always fresh, and I've never gotten even the slightest stomach ache from anything I've ever eaten from this Sonic. Whether it's the same cheeseburger I've ordered 100 times or a brand new special of some kind, most of the time that item will look like it's been dressed for a commercial. And as cool as it is for the food to *look* nice, this also means that you don't have to worry about stuff like getting a burger with mushy ingredients just plopped haphazardly between two buns. It's probably not a big deal to a lot of people and maybe it's something that other people who have worked in food service would notice, but yall - I can count on ONE hand the number of times I've gotten a cheeseburger that didn't have the cheese placed *perfectly*, in such a way that each of the 4 corners stuck out evenly from the buns and the patty. And thanks to the variety of specials that they almost always have running, usually you can get a good meal for a good price. Two very rare qualities in restaurants today, much less fast food places. And did I mention that the staff is friendly and helpful, too? Definitely worth a visit!
