Nerd status: it's a neat concept on their karaoke night - they provide a live back up band!
We were looking for something to do after the Rock of Ages show, attempting to make our way to another casino and BAM we walked right past this place. I saw the "live band karaoke" sign and knew we had to go in; our friends who live in Vegas are HUGE karaoke fans, the husband is a great singer.
So yeah, definitely the vibe of a dive bar... there's beer pong but that's common in Vegas so we were used to it. They had IPA's along with your standard Coors or Bud.
Our server was great - very attentive.
