The Cooper Square Hotel's intimate Second Floor Bar is mixing made-to-order cocktails and delicious classics for hotel guests and locals wanting a peak inside the new Carlos Zapata-designed landmark. The hotel's as slick and modern and mildly unsettling on the inside as on the out: the Second Floor Bar features tiny, ovular tables and chairs, floor-to-ceiling frosted glass door and walls, a soundtrack of spacey indie rock (Flaming Lips, The Stills) and electronic bossa nova and bartender Jigmed Latshang's own inventive, fresh drinks.
