REALLY REALLY busy on game days (Cardinals). Get there early or you will be in a long line.
Luckily, when we arrived, there was no line. They were checking ID's at the door and you had to be 21 to enter? Or they were helping their staff by checking ID's and giving wristbands so you could just order once inside. Either way, no sweat.
It's a typical Yard House - extensive beer selection, but nothing particularly "unique." The food is standard and consistent and the service is fairly fast and friendly.
This entire area is extremely crowded on game days, so be prepared to wait or get there early!
