An exercise in art-deco opulence, The Rivoli Bar's elaborate jewel-box interior will make minimalists break out in hives with its gilded ceiling domes, tone-on-tone marble, camphor wood walls, swirly chandeliers, Lalique glass and leopard-print stools. A byword for luxury, the Ritz's aristocratic charms come at a correspondingly kingly cost: you’ll need to shell out handsomely for a shot of Churchill’s Courage (a Manhattan involving butter-washed bourbon, maple syrup and white port), an Iron Lady (a Champagne cocktail with Bombay Sapphire gin, quinine bark and lime) or the Modern Traveller (Plymouth Gin, spiced water, fig liqueur, Cassis and lemon juice served in a glass pipe). Oligarchs and the landed gentry can swan it with big-ticket bubbles, beluga caviar and luxe seafood platters, while the lower orders get small change from £100 for a bottle of house white Burgundy and a burger.
