Mention Milan to southern Italians, and they will predictably shake their heads and say that the city is too busy and industrial. Those in the know, however, can appreciate how these two qualities are the ideal ingredients for a city that revs up after the sun goes down. The young and upwardly-mobile are on the prowl for after-work hotspots to let off steam, frequenting everything from rooftop lounges to underground monasterial refectories-turned-winebars. Abandoned industrial warehouses have been transformed into social centers, concert venues, and nightclubs. Indeed, the bustling velocity of this competitive town has created a culture of one-upmanship that elevates quality over quantity. And it is in this setting that the world's greatest happy hour, or aperitivo, was born. In almost every bar and cafe across the city, from six in the evening onward, the purchase of a single drink grants you access to a food spread on par with dinner, depending on the venue. While some bars offer finger-food samplings, olives, and foccacia, the more dedicated establishments serve up mountains of risotto and pizza squares, and everything from prosciutto trays to seafood skewers, sushi, and dessert. Start your evening here, with a drink and all-you-can-eat, before migrating to a dark, pulsating dancefloor with international DJs, retro parties, commercial hits, or artsy playlists. Hit up the glamorous big names like Armani and Cavalli, or opt for the hipster, punk, and underground scenes. Whatever your nocturnal taste, Milan is sure to please.
