Fodor's Expert Review Museo del Gaucho y la Moneda
This museum is in a rococo 19th-century mansion near Calle Julio Herrera y Obes, four blocks east of Plaza Independencia. Here you'll find articles from the everyday life of the gauchos, from traditional garb to the detailed silver work on the cups used for mate (an indigenous herb from which tea is brewed). Ancient South American and European coins are on the first floor. Tours in English are available with a couple days' notice.
