Hip, hip, hurray for this ever-fashionable informal Tokyo-style modern sushi joint and slim-hipsters' hangout near Harrods and Harvey Nichols in Knightsbridge. Well lit and designed with polished granite, blond cedar wood, exposed pipes, and open timberwork, Zuma takes in a sake bar, robata grill, and famed open sushi counter—and attracts all the Isabel Marant and J Crew beautiful people from SW7 on a rolling basis. You can't go wrong with the fresh California maki rolls, tuna sushi, sea bass sashimi, pork with yuzo, or robata-grilled Wagyu beef that comes on a hoba leaf. Sip a rare sake, relax, enjoy the superpolite service, marvel at the engrossing petro dollar, Ruski, and spray-tanned "Made In Chelsea" Mwah! Mwah! set, and be sure to collar the sake sommelier to guide you through the 40-odd varieties of exquisite sake rice wines.
