One of the rooms I have been going to lately (Diamond Jim's) did some renovations recently. They added a raised seating area with a rail.
The next time we went in, they had added these handy dandy cue racks!
Some rooms have cue racks near the tables, but this rack is pretty neat because it holds your entire cue! The top is secure in the carved out groove, and the bottom of the cues rest peacefully off the ground!
