His fusion of French and Asian cuisines has led chefs to imitate his pork buns the world over, while his bad-boy persona has earned him friends and enemies alike. Even iconoclasts need a break, though, and when it comes time for his, Chang flees to the wilderness. A novice angler since he was 21 (before that he was a competitive golfer), he takes one big fly-fishing trip out West each year. In September, just as the first of his three ambitious new restaurants in Toronto was opening, he hit the Snake River in eastern Idaho. "On the river I don't think about work," he says. "I can only think about fishing. That's what I love about it."
