This veteran steak house may look stiff and formal, and the patrons may appear stuffy and overfed. But if you think that's all there is to this place, then you haven't been downstairs and outside, where an oceanfront bar serves a group of regulars who arrive in shorts and, well, usually leave in them, too. A big destination for South Beach restaurant-industry personnel, here many of the patrons and staff are on a first-name, first-serve basis. Indeed in the best of traditions, this is the kind of neighborhood bar where everybody really does know your name -- and your business -- at least until the third round or so, that is.
