"The Corner Shop", as Knightsbridge locals call it, is probably the most famous store in the world, selling everything from its ubiquitous green-and-gold branded carrier bags (its best selling item) to a 12.5kg solid gold bar, its latest ultimate luxury accessory. It may not have all the latest fashions these days (look opposite in Harvey Nichols to find those) but it's not far behind and for all but the hardest to please shoppers it's usually a great experience. Harrods began on its present site in 1849 as a small grocer's shop. These days 15 million customers per year come to explore its 7 floors and 4.5 acres. Don't miss the daily cornucopia in the fabulous Food Halls and return by night to see its famous terracotta façade, illuminated by 13,500 lightbulbs.
