On weekdays when it's less crowded, Moonshine can be pretty fun. There's a lot of room for dancing and less drunk frat guys. On weekends? Good god, I can't stand it. It becomes this insane college bar, packed so you can't move, with people standing around wasted pretending to have a good time when no one really is at all.
It's not the worst bar in the world, and it's certainly not the best, but there are much better bars on Mill to hang out at, and much better country bars in Phoenix to dance at. Moonshine is really just "okay."
