Apple is opening the doors to its 300th store tomorrow in London's Covent Garden. According to Apple, it's the best store it has ever created, not to mention its biggest. The Covent Garden store is three levels of brick, steel, and glass and is so big that it can showcase each of its products in separate rooms, while the entire second floor is dedicated to third-party accessories and add-ons. Topped with a massive skylight, this store is something to marvel at and, frankly, puts the flagship San Francisco Apple store to shame. Take a tour for yourself in this photo gallery!
