Santiago's bar scene is anchored in Barrio Bellavista, where the streets around Pío Nono and Constitución fill up with terrace restaurants and clubs on weekend nights. Barrio Italia and Barrio Lastarria have a more relaxed café culture, while the Providencia area around Avenida Suecia has the older, more established nightlife.
Pisco sour is the national cocktail — made with Chilean pisco (note: Peruvians claim the same drink, and the dispute is genuine and ongoing), lemon juice, egg white, and Angostura bitters. The quality varies widely; a good one is worth tracking down.
