CUBS AC in Colonial Lanes is the closest bar to the athletic facilities. Not only that, but the U stands for "Ufer," though I think the Ufer family might have sold its piece.
When the Carver, Ufer, and Buhr bought in, they took great pains to separate the bar from the bowling part of the operation. You know you're in a bar that is attached to a bowling center, but plenty of customers never see the lanes or even pay any attention to them.
It's a great place to get tix on game day, too, without having to deal with the "scalping mafia."
