Osamil Upstairs is on the second floor of 5 West 31st Street in Koreatown, reached by asking the staff at the ground-floor Osamil restaurant to guide you through a service door. The bar holds twelve seats and runs cocktails in the $23 to $34 range, with drinks built around Korean ingredients like omija, a five-flavor berry, and Korean plum.

The bartending team makes bespoke cocktails, which means the conversation about what you want is part of the experience rather than a formality. The aesthetic blends warm dim lighting with Korean minimalism, and the intimacy of twelve seats means the room never gets loud regardless of how busy it is.

Reservations are strongly recommended. It opens at five on weekdays and closes at two on Friday and Saturday. The Koreatown location connects the cocktail program to the neighborhood in a way that feels genuine rather than borrowed.
