Let's go back to the old times by visiting one of these classical theaters in Buenos Aires. I am talking about Teatro Colon (Colon Theater), one of the world's most famous opera houses, possibly second only to the Sydney Opera House.
You should book yourself a concert now, as it is set to reopen (after a long renovation) on May 25, 2008. You should expect performances to be grand as they will be celebrating their 100th year!
