Rookies Sports Bar

No, no, no, no, no, no, no!
If you're reading Yelp, you don't want to go here.  I'm a roguish sort, and I don't care for the place much, but I've been here dozens of times over the years, before it was even renamed Rookies.  
First of all, this is the single smokiest bar on the entire planet.  Spend any more than 2 minutes in this place and you'll reek of stale secondhand smoke.  Gross.  The bathroom is positively nasty.   I can't tell if the ammonia smell is from cleaning products seldom used, or from urine.  Either way, it's certainly no "rest"room.  
They do have relatively inexpensive prices.  Beer and cocktails alike are very reasonable.  They host karaoke and have live singers/bands every weekend.  Truth told, the entertainment is pretty good.  The biggest problem lies elsewhere.
The folks that frequent this place are not a savory lot.  This is a place that opens early in the day and the construction crews, bikers, and general blowhards arrive with the opening and they begin drinking... heavily.  The folks at this place frequent several of this same type bar up and down Ft Campbell Blvd, you'll see the same characters at about 4 or 5 other places, but that's irrelevant.  Look at someone the wrong way, say the wrong thing, or just be in the wrong place at the wrong time and you're in for trouble.  
This is a place for people with only the thickest of skin.  Unless you're a professional wrestler, you should avoid this place.  I've seen too many fights, assaults and the like in this place.. among women, too!  There aren't many quality places to have a nice time with cocktails in Clarksville, but regardless how desperate you get, don't go here.
