There was once a time when venturing south of the Thames “would bring a Chelsea girl out in hives”, says Tatler. But nowadays, the “deep, deep south” – Peckham, Camberwell, Brixton and the like – is the “new epicentre of London’s elite”. Westminster types no longer plot in Mayfair’s member’s clubs, but in the “bougie gastropubs of Greenwich”, home to the new PM and Chancellor. A “younger, edgier crowd” prefer Peckham: Bellenden Road, with its “toff-filled restaurants” like Artusi and The Begging Bowl, now far surpasses King’s Road. Expect the same ambience in Brixton, where your neighbours would include both acting royalty (Joanna Lumley) and real royalty (Prince Fritzi von Preussen, a descendant of Kaiser Wilhelm II). Suitably cool pastimes include dancing to techno at Phonox nightclub and catching stand-up sets at the Cavendish Arms, or, to locals, “the Cav”.
