K-pop, hip-hop and a social room behind the Hamilton Hotel.
The Mansion is a lounge and club on the second floor of the Hamilton Hotel's main building. A bright red entrance opens into a room with banquette seating, standing tables and a bar, mixing a place to gather over drinks with space for a louder night.
The night, up close.
K-pop, hip-hop and familiar pop tracks shape the party atmosphere. Visitors describe a mixed Korean and international crowd, with room to talk earlier and dance later. Crowds depend on the night; recent visitors also describe quieter lounge-like evenings.
