Dubai still has lots to offer away from the sandy dunes. The booming middle-eastern business center offers the 7th largest shopping mall in the world, the Dubai Mall. In addition, since 2010, Dubai is home to the world's tallest building; the Burj Khalifa in downtown Dubai. The spectacle of desert opulence and grandeur continues in the souk districts along the Dubai saltwater creek, which are home to hundreds of gold retailers, and an estimated 10 tons of gold at any given time. After an eye-opening night of gold shopping, Dhow cruises are a popular way to relax and see the sights alongside the creek like the Chamber of Commerce and the Diera Twin Towers.
