The London restaurateurs Jeremy King and Chris Corbin are best known for the Wolseley, their grandiose and wildly popular Viennese-style café on Piccadilly. For their first hotel, however, the partners of more than 30 years veered from the high-profile path, selecting a tucked-away location on a quiet lane off Oxford Street in Mayfair. The Beaumont (thebeaumont.com), which opened last October, is suitably low-key for its setting yet confidently luxurious, the kind of place where regular visitors to London might store a couple of Savile Row suits for future stays. The hotel’s 73 guest rooms include 23 private-club-like suites, each of which unfolds as a collection of distinct spaces rather than a multipurpose box. The New York–style Colony Grill Room and American Bar are hidden behind discreet doors off the lobby, while the Cub Room—a bar reserved for Beaumont “residents”—is secreted away farther still. All this exclusivity, of course, need not shut out guests from the liveliness that is London. Despite their covert location, the public bar and restaurant have become popular with locals. And just out from the Beaumont’s front entrance, guests can glimpse the grand facade of Selfridges—the bustling heart of the Oxford Street shopping scene—a half block away.
