Nightlife in Buenos Aires can be very exciting. After having dinner, you can see a movie, meet with friends in a bar or café, or just drink the night away. Plaza Serrano located in Palermo Viejo is the hippest place to be in town and to be cool about it.
Some places that are cool to go to are Acabar, Asia de Cuba which is basically Japanese food, Bahrein, Bar Sur for an excellent tango dance show, Deep Blue, Maluco Beleza which is another old mansion, Notorious, one of Bueno Aires leading jazz areas, and Pacha, named from Ibiza.
