The Apple flagship store on Fifth Avenue is open 24 hours a day making it truly one of the most unique computer stores in the city. The store has become a favorite destination for New Yorkers and people around the world. It is always crowded during the day and I find it most convenient to shop at this store late at night. One of the most photographed structures in NYC, the store's signature glass cube was created by designers Bohlin Cywinski Jackson and structural engineers Eckersly O'Callahan (glass elements). The 32-foot structural glass cube marking the store's entrance makes a bold architectural statement, and easily entices plaza level passersby down to the store's underground main level.
