Will Smith's Miami is filled with supermodels in thong bikinis holding fruity drinks with umbrellas in them, dancing salsa. But if you head downtown for lunch at Morton's of Chicago, you find a very different kind of Magic City: corporate executives in tailored Armani sipping martinis, cutting deals to canned, easy-listening jazz. The twenty years this steak house chain has been serving USDA prime porterhouse steaks to movers, shakers and other future heart patients is really something to rap about. Smith might not know to git jiggy with it, but the power suits who make the city run over filet mignon are the ones you want to hear say, "Welcome to Miami."
