I waited 30 minutes to get my cheeseburger, shake, corndog and cheesy tots!!! I had to buzz in to ask where my food was.

This location is supposed to be open at 7 am but every time I've been there around 7.15 it's never open! It needs to check when the employees show up! Terrible

I love this Sonic location. My trainer wouldn't be happy to know this but I'm a regular customer here. The staff here is awesome for the most part. There is a female named Brittney who is always so sweet whether she's working drive-thru or the drive-up slots. It's really a pleasure to be greeted at a fast food restaurant like a real person who they care about, just as you would by a hostess or waitress at a dine-in restaurant. The service is slow, just as it is at any other Sonic because their food is made-to-order and very fresh so I don't consider that a thumbs down but it's worth mentioning to those reading this who don't understand made-to-order quality "fast" food.

The O'Fallon IL location twice now has forgotten items on the order and also the receipt. When going through a drive-thru employees need to confirm the order is filled and CORRECTLY. Yes, it's a drive-thru, and yes it's sonic but still, get it right or shut it down!
