For most people, karaoke is something done only in the privacy of the shower or when your friend drags you (with your fourth or fifth vodka tonic in hand) to the stage to giggle through an ensemble rendition of "Girls Just Want to Have Fun." But for the few and the proud, karaoke is an art form. And there's no better place to practice that art than at Music Bar, where the karaoke is on three nights a week (Thursday, Friday and Saturday) and where your chances of getting multiple turns at the microphone in a single night are better than at other karaoke mainstays — in between renditions of "Girls Just Want to Have Fun," of course.
