Buenos Aires is deservedly known as the town for tango, but if you want to learn the dance of passion in an authentic and nonthreatening environment, head to Rosario. Here, near the riverfront, on Calle Corrientes 152, you'll find the cavernous Barrio de Tango. Every night, from 8.30pm onwards, they hold group tango classes. The teachers throw you right in the deep end - and by the end of the first half an hour you'll be hot-footing it around the dancefloor led by one of the regular attendees. Many of the regulars here are oldies - but hell are they goodies. These men sure know how to manouvre a señorita around a dancefloor. The odd left-footed tourist also makes an appearance here, as well as 14-year-old girls preparing for their big 'public' dance with their fathers at their 15th coming-of-age birthday parties.
A night of tango classes costs 10 pesos (around US$3). Check out www.sentimientotango.com.ar for more information.
