Mining the past is, generally, best left to historians: among many in the hospitality world, this is the received wisdom, anyway. But how deftly Chris Corbin and Jeremy King disprove it at The Beaumont (www.thebeaumont.com; from £395), on a hidden square in London’s Mayfair, where a very specific narrative of the past is brought to fulsome and eminently stylish life. King based the concept here on a fictitious character he christened Jimmy Beaumont, a Prohibition-era hotelier whose fabled aesthetic informs every last detail, from the elegant 1920s portraits in the lobby to the menu in the Colony Grill – where delicious nostalgia reigns, in the form of lobster à la Russe and iceberg-wedge salad – to the monogrammed playing cards in the rooms. A special nod to King’s partner in business and life, Lauren Gurvich King, whose exquisitely attuned eye for a perfect vintage find accounts for the flawlessly credible interiors. This place is elegance like they don’t do it any more.
