"In a city full of stuffy clubs for the elite, the SKC (as it's called) comes as a welcome relief. It's tapped into the wellness scene and created a cozy, comfortable, classy home away from home for the health-obsessed. Here members can drop in for a whirl around the world-class Russian baths, have a quality massage or facial, sup on avocado toast and green juice, and hit the gym after with some of the best trainers in town. (The sessions with Paola of Paola's Body Barre are our favorites.) In the evening, you can check in upstairs for a lecture on some remote part of the world, given by the Voyager Club—and you can also book trips through them to, say, the Arctic—and then head to the DJ booth for late-night drinks and dancing. It pretty much ticks all the boxes for the cool and well-to-do down in Chelsea, South Ken, Holland Park, and beyond."
