The easiest way for Viennese to experience sleek, suave, New York–style power dining—short of paying for a round-trip plane ticket—is to book a table at this Italian hot spot in the heart of Vienna. If they can, that is. Wait-listed weeks in advance, this modernist extravaganza has brought a touch of big-city glamour to Alt Wien, and everyone from foodies to fashionistas loves it. Seafood is so fresh it's flown in daily for the kitchen to prepare specialties, such as shrimp marinated in lemon and served on a bed of Tuscan beans, or roasted sea bass in a couscous salad of cucumber and avocado. For beef eaters, the chef prepares a special piquant sauce poured over a rib-eye steak.
