Annabel's > Rupert's
The old haunt Annabel's, queen of the scene, in Berkeley Square.
The new arrival Rupert's, a swanky, invitation-only members' club in Mayfair. According to owner Robin Birley, 'It's a dinner and dance. Not a disco.'
Who's on the guest list? Old-school boys and well-heeled society gals rubbing shoulders with Russian oligarchs and Middle Eastern princes.
Who's not getting in? Footballers' wives? Forget it.
What's the damage? Yet to be set.
Talking point? Tuck into the oyster bar, marvel at the varieties on offer at the in-house cigar shop and admire the Rifat Ozbek-designed dining rooms.
Be there 55 Shepherd Market, W1. Opening autumn 2011.
Boujis > Public
The old haunt Boujis, the South Kensington club that made the Sloane set look more glamorous than they ever imagined.
The new arrival Public. Bigger and better than Boujis, this new industrial-style loft space is New York meets Chelsea. The music plays second fiddle to the see-and-be-seen crowd.
Who's on the list? Young royals and that Sloane set.
Who's not getting in? Over-30s.
What's the damage? £10 entry.
Talking point? Have a canter on the resident merry-go-round horses or unleash your alter ego in the fancy-dress room.
Be there 533 Kings Road, SW10 (public.uk.com)
Fabric > The Nest
The old haunt Fabric, Farringdon's original superclub.
The new arrival The Nest is Dalston's response to commercial clubbing, recently opened to showcase underground talent and cross-genre music nights, plus the odd poetry and theatrical event.
Who's on the list? Hipsters on the hunt for the next big thing.
Who's not getting in? Those who don't look good on the doorstep.
What's the damage? Usually free before 10pm, £5 after.
Talking point? Check out the 70s erotica décor. Plus 20 per cent of bar profits will be donated to The Nest bursary, which grants a monthly cash award to a deserving creative project.
Be there 36 Stoke Newington Road, N16 (Ilovethenest.com)
Madame Jojo's > Playboy Club
The old haunt Madame Jojo's, home of high-kicking glamour.
The new arrival Playboy Club. Almost 30 years since Hugh Hefner's Playboy empire quit London, the bunnies are back. This retro relaunch promises to stick to the original ethos, summed up by Hefner, as 'good food and drink, pretty girls and exciting entertainment'.
Who's on the list? Original 1960s clientele included Sean Connery, Michael Caine and Joan Collins, so expect a roster of A-list jet-setters.
Who's not getting in? Anyone appearing regularly in Heat or OK!
What's the damage? Yearly membership is £1,200 if you pass the rigorous vetting process.
Talking point? Mixologist Salvatore Calabrese will open his bar Salvatore's here. As with the rest of the club, it will be run on an exclusive members-only basis.
Be there 14 Old Park Lane (playboyclublondon.com)
