Nightlife -- or la marcha -- reaches legendary heights in Madrid. It has been said that Madrileños rarely sleep, largely because they spend so much time in bars -- not drunk, but socializing in the easy, sophisticated way that's unique to this city. This is true of old as well as young, and it's not uncommon for children to play on the sidewalks past midnight while multigenerational families and friends convene over coffee or cocktails at an outdoor café. The streets best known for their social scenes, however, do attract a younger clientele; these include Huertas, Moratín, Segovia, Victoria, and the areas around the Plaza Santa Ana and the Plaza de Anton Martín. The adventurous may want to explore the scruffier bar district around the Plaza Dos de Mayo, in the Malasaña area, where trendy, smoke-filled hangouts line both sides of Calle San Vicente Ferrer and of Calle La Palma. A few blocks east are the haunts of Chueca, where tattoo studios and street-chic boutiques break up the endless alleys of gay and lesbian bars, techno discos, and after-hours clubs.
