Marcus SamuelssonThis Top Chef Masters winner's Instagram feed shows him palling around with some of the world's most famous chefs (including Andrew Zimmern, top right), attending royal weddings, participating in ping-pong tournaments and generally having the time of his life. Instead of photographing his own food, he prefers to showcase the meals he eats at others' restaurants. Marcus Samuelsson, @marcuscooks
