I recommend coming here with a group of friends (reserve a karaoke room ahead of time) during happy hour. Get some appetizers, enjoy some drinks, and sing like no one can hear you- they probably can't.
Drink recommendations: Blue Barrymore (blueberry martini) and the "I'm Turning Japanese. Careful though, they may not taste super boozy- but they are! Which makes singing with your buddies all the more fun :)
