For more than 60 years, SONIC, America’s Drive-In has built the ultimate dining experience with our drive-in restaurants and we proudly serve our guests in St. Charles, MO. We did it by sticking to what made drive-ins so popular in the first place: made-to-order American classics, signature menu items, and speedy service from friendly Carhops full of fun and personality. Cruise on over to us at 3851 Elm Street for the ultimate SONIC experience!
Two times in a row my father and I visited this location and were met with a hostile lady working the drive through. She was very rude and argued with us about what's on the menu right in front of us...
Won't be coming back.

Placed order at stall with employee, kiosk was out of order. Waited 30 minutes, recueved no food or explanation before leaving. I'm patient, so just an explanation that someone went wrong would have been helpful.

I have such a soft spot for this Sonic, but visiting lately has become a bit of an obstacle course. I’m writing this in the hopes that they can give this location the comeback it deserves! Of course that requires more business I’m sure.
The Atmosphere & Property:
To be honest, the lot is in pretty rough shape. You really have to keep your eyes peeled for the potholes—some of them are incredibly deep and definitely not friendly to your tires. Additionally, it seems like a large number of the drive-in stalls are either closed or just flat-out non-functional, which limits where you can park and wait. It definitely feels like the exterior has been neglected for a while.
The Food & Service:
Despite the state of the parking lot, the kitchen is still holding it down. The mozzarella sticks were perfectly fried and melty, and the cherry limeade still hits the same—it’s that classic, refreshing taste that I was craving. I don’t usually eat fast food, but I was not disappointed with the snack!
Final Thoughts:
I really hope they can invest some time and resources into fixing the pavement and getting the stalls back up and running. This location has so much potential and the food is still great, but the "off-roading" experience just to get a snack is getting to be a bit much. I’d love to see this spot get more business and maybe bounce back!
