Osamil Upstairs is a hidden speakeasy-style cocktail bar located on the second floor of Osamil restaurant at 5 W 31st Street between 5th and 6th Avenue in Manhattan's Koreatown, accessed through an unmarked service door behind the main dining space. The modern Korean-inspired cocktail program blends traditional flavors with contemporary mixology techniques, featuring drinks incorporating yuzu, matcha, and soju, such as the notable banana-milk cocktail offering a soju-spiked take on banana cream pie. The intimate 12-seat bar and lounge-like private areas create an upscale yet approachable atmosphere; cocktails range $23–$34 and table reservations fill quickly, particularly on weekends.
