Some of the nicest, coolest and expensive bars are located in San Isidro and Miraflores districts: Las Brujas de Cachiche, Bar O, Bohemia, Astrid&Gaston bar.
If you are looking for some laid back bars, with wooden tables and chairs, good music and lots of beer, go straight to Barranco. There are plenty of bars around the main plaza. All time favorites: La Noche (www.lanoche.com.pe), Mochileros Bar, La Posada del Angel.
Special mention: a bar with social responsability: Voluntarios Pub (www.voluntariospub.org). This place is unique: it combines great environment, music and drinks with volunteerism and social commitment, as all the revenues are donated to non profits. It is run by a civil society organization, and all waiters are volunteers that rotate and come from or help the non profits that receive the funds. It is a great success!
Visit Cafe Haiti, the best coffee in town and also a 50 year place, with his own history and personality. It is located in front of Parque Kenedy in Miraflores.
High end discos: Gotica and Aura in Larcomar (Miraflores). Entrance fee is around USD15.
If you want a more relaxed environment, you can dance at La Noche (dancing starts around 1am), Voluntarios Pub or La Sede (also gay friendly).
