Miami's hotly anticipated Setai hotel is launching with an Asian-themed spa—complete with irresistible food.

Asian-themed spas are the latest must-have amenity at luxury resorts. The most ambitious new U.S. property with such a spa is The Setai in Miami's South Beach, managed by GHM, the company run by Aman founder Adrian Zecha. The resort includes a 40-story condo tower, a 75-room Art Deco hotel and a 10,000-square-foot spa offering innovative treatments influenced by Thai, Balinese, Malaysian and Himalayan traditions. Chef Shaun Danyel Hergatt, who oversees the Setai's four restaurants, creates healthy Asian dishes, like the ones here, geared for spa guests (888-625-7500).
