Make friends with locals because members-only clubs are very popular in the UK. Soho House has multiple London locations, all of which are reliable bets; Little House Mayfair is great by day (especially if it's warm and you're seated next to the open windows), as is the original location, which is located in Soho and has two outdoor spaces. By night, Electric House, which is adjacent to the oldest cinema in London, is very popular. Also worth singling out is Shoreditch House, which is located in East London and has a very popular rooftop pool.
Loulou, another member’s only club located in Mayfair, is also a popular option. Prince Harry and Rihanna are fans of the Rose Club, a diminutive spots located in the heart of Mayfair, while Radio, located on the rooftop of the ME London Hotel, 2&8 Club and Le Baron London all consistently generate buzz.
If it’s a truly British after-dark experience you’re after, however, head to Dukes bar. Legend has it that it’s where Sir Ian Fleming coined the catchphrase “shaken, not stirred” for his James Bond flicks.
