Cosmopolitan in flavor, Russia's capital exudes prosperity and vigor. From Stalin's carved-marble metro stations to the sprawl of modern business complexes, Moscow flaunts its ambition, and often goes over the top. It's an all-night-party town whose days offer endless opportunities for those who can keep up. A merchant capital by birth, Moscow was made for big spenders, and money has always made the wheels go round here. In what's now one of the world's most expensive cities, the only possible limit is the size of your wallet.
