Atlantis is the majestic focal point of Palm Jumeirah, a man-made island that has captured the world’s imagination. The 114-acre Atlantis Dubai is, like the Atlantis Bahamas, an oversize extravaganza: 1,539 rooms, a water playground with rides, a dolphin habitat, and a 6,200-square-foot spa. Star chef Santi Santamaria’s Ossiano restaurant, his only venture outside of Spain, is submerged in a 3 million–gallon manmade lagoon, home to 65,000 marine animals.
