It’s a to go place when you are hungry for fast comfort food. Chicken tenders were dry and tough, though.

Perfect stop on a hot day to enjoy my favorite drink from sonic, a large cherry limeade. It’s just something about enjoying it on a hot day that makes it worthwhile. Our carhop was nice and ensured we got everything needed. And don’t forget the Mozzarella sticks with marinara sauce!

This location is horrible. Employees are rude and the ice cream is always nearly melted by the time they make it to to your car. The location on Cross Timbers is much better.

Utterly unhealthy food..typical artery-clogging, batter-fried selections. I checked the nutrition on even their “healthier” selections, and let’s just say their version of healthy is far different from mine. I stopped eating here when I checked their ingredients and nutrition. Good for a 44oz iced tea during happy hour, but otherwise I avoid this place like the plague. They keep their patio fairly clean, and the carhops are friendly. I wish there was something there I felt safe eating.

Drinks were good. Fries and tots were cold and stale. Bun on the burger over heated/brown/hard and Luke warm.

Drinks are always good which is why my family went but the car hop was unfriendly which just ruins the overall experience. It’s cool with me if you don’t like your job, find a new one, but while you’re on the clock working, your paying patrons shouldn’t need to feel your attitude.

Second time this week I order my food and either my fries or tater tots are not even cooked. Who wants to eat soagy tater tots? I don’t and I sure in the hell won’t buy anything from this location again!

Didn’t realize they open at 7. Showed up early and they still took my order. I have been coming here for years and they always have great employees. Super friendly and fast.
