This giant, bustling store (the second-largest in the U.K. after Harrods) gives Harvey Nichols a run for its money as London's most fashionable department store. Packed to the rafters with clothes ranging from midprice lines to the latest catwalk names, the store continues to break ground with its innovative retail schemes, especially the high-fashion Superbrands section, the ground-floor Wonder Room showcasing extravagant jewelry and luxury gifts, the self-contained Louis Vuitton town house, an array of pop-up shops, and the Concept Store, which features a rotating series of themed displays. There are so many zones that merge into one another—from youth-oriented Miss Selfridge to audio equipment to the large, comprehensive cosmetics department—that you practically need a map. Don't miss the Shoe Galleries, the world's largest shoe department filled with more than 5,000 pairs from 120 brands, displayed like works of art under spotlights. Take a break with a glass of wine from the Wonder Bar, or pick up some rare tea in the Food Hall as a gift.
