With an encyclopedic assortment of luxury brands, this Knightsbridge institution, currently owned by the Qatar Investment Authority, has more than 300 departments and 25 eating and drinking options, all spread over 1 million square feet on a 4½-acre site. Now populated more by window-shopping tourists and superrich visitors from abroad than by the bling-averse natives, Harrods is best approached as the world's largest, most upscale, and most expensive mall. The dining hall offers on-site dining options that include a Pasta Evangelists' Italian spot, fish-and-chips by noted chef Tom Kerridge, a ramen bar, a sushi restaurant under the auspices of sushi guru Masayoshi Takayama, and a Mediterranean grill, plus a rooftop restaurant serving Nordic cuisine, a pan-Asian fine dining restaurant, a patisserie, a dim sum terrace restaurant, a Gordon Ramsey burger bar, and a Moët & Chandon champagne bar, while downstairs there's a restaurant from Michelin-starred chef Jason Atherton. There's also a giant coffee-roasting station, ceiling-high shelves of fresh bread refreshed every half-hour at the Bakery, and a Chocolate Hall. The Beauty Hall offers cult brands, innovative "Magic Mirrors" that allow shoppers to instantly see a new makeup look via digital technology, an in-house "hair doctor," and more than 46,000 different lipsticks, as well as 13 treatment rooms where you can try on makeup in private, suites for facials and body treatments, and even a piercing salon. Most ultra-luxe international designers such as Vuitton, Chanel, and Hèrmes are represented, but even this temple to money-is-no-object shopping has embraced sustainability: there's a designer rental service in conjunction with My Wardrobe HQ.
