Mandarin Oriental, Las Vegas
At the 392-room property, interior designer Adam Tihany tries to re-create the experience of contemporary Hong Kong. When guests step off the elevator at the 23rd-floor lobby, they encounter what he calls a “gold bullion wall,” a shimmering blast of gilded geometry. For more gold, the hotel achieved LEED Gold certification, acknowledgment of the complex’s energy- and resource-conserving features. The spa offers 17 treatment rooms, yoga classes, and a Kinesis Fitness System; the property's five restaurants and bars include Twist by Pierre Gagnaire, the Michelin-starred chef’s first U.S. venture.
