A two Michelin-star restaurant of near-unfathomable opulence, The Ritz is one of London’s most lavish restaurants, known for its grandeur as well as its impeccable service. Food comes from the mind of executive chef John Williams, every part a chefs’ chef but one who knows what it means to cook for people seeking food worthy of a special occasion. If nothing else, go for an enlivening menu of fine British meat, fish and game, and, for those not abstaining post-Christmas, a glass of champagne and a bottle of something lively. It is rare that spending £500 on dinner would seem fair. At The Ritz, it really is.
