Having opened in 2010, Ai Tunes Karaoke is the perfect place to have a singoff, whether it's just with a few friends or a an entire group outing. It offers nine private rooms, more than 50,000 songs in multiple languages, and a full restaurant and bar. Private karaoke rooms start as low as $20 an hour, and drink specials are available almost every day, if you need the "liquid courage" to sing in front of a crowd.
