Yep. I went to the one in Cottleville, MO (also near St. Louis) about 11am and it was jammed - line out the door & down the sidewalk - drivethru all the way around, and yet they were doing great with service - they must have had 20 people behind the counter!
I thought about asking my wife to stop there on her way home from work, but that wouldn’t be fair to her. We’ll keep it going tomorrow.
I wonder how the one is on Highway K in O’Fallon.
