With its ultramodern skyline, it's easy to forget that Dubai, part of the United Arab Emirates, was once a small town of Bedouin traders. Now the old mixes with the new: At the Nad al Sheba racetrack, camels race by day; thoroughbreds at night. High fashion and electronic stores are as popular as the gold souk. A sampling of the 400-plus restaurants gives you a taste of Dubai's ethnic diversity. Come enjoy the beaches, golf, historic sites, nightlife and renowned tax-free shopping of Dubai.
