Few émigré Americans checking in to what is now The London Marriott would have foreseen that the hotel's basement repository would host a totally above-board take on their moonshine-fuelled illicit speakeasies back home. The Luggage Room’s polished art-deco design even references the silk-lined monogrammed Louis Vuitton steamer trunks once deposited within. Top-dollar 'lost and forgotten' cocktails include Gin Punch à la Terrington (a 19th-century high-society sip involving lemon sherbet and green Chartreuse), as well as numerous cups, coolers, swizzles, imperials, nogs and flips. It’s also worth considering signature sips such as the Barney Barnato: named after a charismatic Victorian precious gems prospector, this well-balanced barrel-aged mix of pisco, vermouth, Curaçao and bitters makes for a diamond drink. 'Low tea' – a revived Victorian tradition – is a new afternoon treat served at this clandestine hole-up.
