Informal tango in Plaza Dorrego Buenos Aires © Judith Duk
Plaza Dorrego lies in San Telmo, the bohemian artists' quarter of Buenos Aires and the birthplace of tango. The tiny square is surrounded by elegant houses, now mostly converted into antique shops and bars whose tables overflow onto the street. There are numerous excellent museums nearby, including the Museo Histórico Nacional and the Museo de Arte Moderno. On Sundays, the plaza hosts the Feria de San Telmo. You won't find too many bargains, but you may find an interesting souvenir or two. Once the stallholders pack up their wares, the square becomes a stage for informal tango dancing, popular with locals and tourists alike.
