Karaoke??

So a couple years ago one of my bridesmaids rented out a back room at a karaoke bar for her birthday in NYC. I'm not friends with her anymore but I also don't want to do NYC. Does anyone know a place that I can do this on Long Island, would prefer to be in Nassau county. PLEASE HELP! We want to do something the night before the church wedding and I thought this would be fun!

EDIT: It would be a Saturday night. Not the whole bar, just a back room that lets you do your own private karaoke party.

There's a place in Bohemia...I have never been so I can't say what it's like...they have packages for either karaoke or a DJ:

Lizard Lounge

Good luck finding something!!
