Sonic Drive-In is a new spot with a retro vibe and modern cleanliness. The service was incredible, with friendly staff. The jalapeño burger was amazing, but the popcorn chicken was a bit lackluster. However, there were some hiccups with the orders, like receiving the wrong drink and missing condiments. Overall, a good place to grab some typical Sonic food, but they may need to focus more on training to improve the service.
