The city of Miami, Florida is set to build a $4 billion mega-mall called the ?American Dream?. Spanning 6 million square feet, it will be the largest mall in the United States. Reports say it will look more like an amusement park than a traditional, dumbbell-shaped mall. The complex will feature a water park, an indoor ice rink and an artificial ski slope. In addition it will contain dozens of restaurants and up to 1,200 stores.
