Replacing what was Bar 16, the Flat—a posh, late-night locale—is trying to find its niche after being open for two months. Proof of this is its ever changing clientele, which ranges from bridge-and-tunnel folks on a Saturday to the occasional hipster during the week. Two V.I.P. areas even found the likes of Pharrell Williams of the Neptunes, who threw a private party there recently, along with industry types chilling among the red banquettes, white hanging lamps, and gilded walls with blue swirls. On a regular night, the music is as varied as the crowd, with pop tunes, rock, hip-hop, and then some. A menu of finger foods, including a decadent cheese plate for $10, and surprisingly cheap drinks (a strong vodka gimlet and raspberry Stoli with cranberry both cost $8), make this place a find. Even if it hasn’t figured out who it’s catering to yet, the place has lots of potential.
