Considered outdated for many years, it has once again has become a very fashionable dance in Buenos Aires.

Paris, Berlin, New York and many other world cities followed that trend soon - Tango schools are appearing everywhere and start to offer tango lessons to even the youngest. This is one of the reasons why Buenos Aires is the favourite travel destination for many Europeans and Americans.
