Relatively new on the scene, and, yes, underground on 54th Street, this is Broadway’s cabaret. What that means is the vast majority of performers are playing hooky from their real jobs at the big Broadway houses nearby. They’re often trying out new material, giving the shows a joyously loose feel, but because the talent is so stellar—Andrea McArdle, Tovah Feldshuh, Judy Kaye, Randy Graff, all took the stage here in 2015—it never feels like a rehearsal. In late 2015 cabaret legend Michael Feinstein became a partial owner of the club, bringing with him many of the musical talents who had performed at his uptown club (he himself does gigs every month or two, along with such stars as singer Andrea Marcovicci and comedian Norm Lewis). Theclub itself is charming, with a 1930s speakeasy decor, much better food than necessary, and great sightlines.
