Food was great. Workers were extremely rude which was disappointing since i love our sonic. I was repeatedly ignored while trying to clarify my order, my drink was messed up and when i asked for the sauce i asked for (three times during said order) i was given a large bag of 15 sauce cups and rudely waved off. Very disappointed.

I went through the drive through for shakes (mostly because my last experience at a Sonic in Southern Illinois with the park and order was horrible) and waited way too long for 2 shakes and a cup of ice cream. It was also not very clear where to go, so I wasn't even sure if I was waiting on the right spot until about 10 minutes went by and they brought another cars order. I was hoping for the experiences I had in Georgia at Sonic, but I'm seeing none of these Illinois locations are it.
