Mahiki Mayfair

It's worth remembering that, before it turns into a full-on party, this doolally 1950s-style Polynesian cabana is a civilised spot for a sundowner. Mayfair legend Mahiki is not the place for an Aperol Spritz, but they'll make one if you really must. The big attraction here is a line-up of rum punches, grogs and slings with names like Bikini Blast, Krakatoa, Bajan Whirlpool and ‘vicious’ absinthe-spiked Baron Samedi's Brew – all served in assorted tiki vessels. Otherwise, Armada Treasure Chest and Queen Ann's Revenge (a magnum of Cîroc, two bottles of Cristal and 20 shots) are the sort of fishbowls that would feature large on Sun, Sex and Suspicious Parents were the grown-ups snooping on their misbehaving progeny in Antigua rather than Ayia Napa. Asian snacks act as damage limitation as the action heats up in the downstairs club.
