Valparaíso has an inordinate number of late-night establishments, which run the gamut from pubs to tango bars and salsa dance clubs. Thursday through Saturday nights most places get crowded between 11 pm and midnight and young people stay out until dawn. The main concentrations of bars and clubs are on Subida Ecuador, near Plaza Anibal Pinto, and a block of Avenida Errázuriz nearby. Cerro Concepción, Alegre, and Bellavista have quieter options, many with terraces perfect for admiring the city lights.
Tango dancing is so popular in Valparaíso that you might think you were in Buenos Aires. Then there's the cueca brava, a common Chilean song and dance (also called cueca urbana or cueca chora in these parts); it's undergone a revival in recent years, taking on a much more modern and urban slant.
