If you want to really have a great experience during your trip to Buenos Aires, do not miss the fabulous show of Complejo Tango. I lived in Buenos Aires for 4 months and had the opportunity to go to many tango shows but Complejo Tango's show was the best, hands down. Not only is the show excellent, the food is wonderful, you get an hour of dance class where you get to learn the basic steps of tango, and the people that work there are truly amazing, beautiful people. The all-round experience is something that should not be missed. Aside from the dinner-show that runs everyday of the week, you may take group classes or individual classes with incredible instructors any day you wish. I took classes at least 4 days a week there and would have taken more if I could have. It was the best experience of my life and I will go back as soon as I get the chance.
