I go to this bar, simply because it's right across from the UNLV campus. I mean, who doesn't enjoy throwing back a couple beers in between classes? It's what makes all my classes bearable.
This place does have an amazing selection of beers. I'm not a big fan of their prices though. They do offer a happy hour, but it's nothing special. But, the Frog provides something that most of the other bars I go to provide: live entertainment. From Jazz nights to open mic nights - it's a great place to go to expose yourself to music you might have never liked.
They do have a smoke free policy, which always bothers me when it comes to bars. But, all in all, good place to go to if you're in the area - but definitely not a place I would go if I had to drive out of my way for it.
