Larry Golden of Pianos, musician Andrew W.K., and artist Spencer Sweeney’s highly anticipated new club/lounge/performance space, goes by many handles: Santos’s Party House, 100 Lafayette, and formerly Santa’s Party House. Hidden past a flight of blue stairs, beyond a multi-colored room, lies a space three years in the making. Given the extended build-up, the décor disappoints: painted blue walls and disco balls does not a legend make. Lucky for Santo’s, the mix of hipsters, ravers, bankers, and old eccentrics don’t seem to care, and the impressive list of DJs already signed up to spin will ensure that this summer hot spot earns its reputation fair and square.
