Sleek, elegant, and old-school, Cuckoo Club is a shining example of glamorous London nightclubs done right. It's the after-party spot for West End designers (Carmen Dell'Orefice, the world's oldest working model and first ever supermodel, has graced the premises during London Fashion Week) and Mayfair sophisticates. Depending on the night, you could be dancing on tables (the Ibiza DJ set frequents the decks most months), or politely sip Belvedere. Though a member's club, you'll be able to snag a spot on the guest list with a little advance notice, so grab some friends and practice your seat-dancing – you'll be there til the sun comes up over Regent Street.
