- If it's the tango that is your obsession, you definitely must visit La Viruta Tango. This café-cum-bar and nightclub is a livewire. Every night you'll find young clubbers swaying and dancing to the tunes of tango or milonga numbers from the '60s, '70s and '80s. Also, you can register yourself for some classes that are held by professional dancers. Enjoy occasional performances by local bands, and take part in competitions that happen almost every week. If you feel the need to take a break, eat at the restaurant that serves up Italian snacks, wines and a whole lot of vegetarian choices. Then return to burning up the dance-floor!
