Idle Hour Club

Tons of pool and snooker tables, usually a good crowd (only bar in town, except for Scooter's, but that's a technically a club).  Biggest downside is the crazy amount of smoke inside, but when the back door is open that's not so bad (winter is another story).  

Bars in Clay County can't serve hard alcohol so you're only able to order beer and drinks like Mike's Hard Lemonade.  They do serve their beer in frosted mugs, big plus on that.

If you're in Clay Center and looking for a drink this is basically your only choice, but it's a pretty good choice to have.
