Tango
A trip to Buenos Aires is not complete without some sort of experience of the Tango, the national dance of Argentina. A good place to go and watch some authentic Tango is at the Confiteria Idéal Suipacha 384 (just off of Corrientes, near Calle Florida. However Tango is best experienced not in La Boca and on Calle Florida, but in the Milongas. A milonga is both a place where a Tango dance will take place, as well as a specific type of tango dance. Milongas take place either during the day or late at night. "Matinée Milongas" usually start in the early afternoon and go until 8-10PM. They are popular with tourists who may struggle staying up until 5AM every night. Inside a milongas, you will find many locals who will be more than willing to show you how to dance. The night Milongas officially start at around 11, but don't fill up until around 1:30. They may go on until 5 or 6 in the morning. Some Milongas to note are: Salon Canning, El Beso and Porteno y Bailarin.

Lessons: You can start learning tango through the group lessons offered at many studios. Some popular schools are at the Centro Cultural Borges, on the very top floor. It can be very hard to find the actual place as there are some stairs you have to go up, and then you have to go through a museum. Ask the security officer where the "Escuela de Tango"  is. Take note that in the summer time the rooms can get very hot. The Centro is within the Galerias Pacifico, the American-style mall near Calle Florida on San Martin. The best way to learn, even if you do not have a partner, is with private lessons. You can find instructors who charge as little as 50 pesos per hour, all the way up to ones that will charge 368 pesos ($100) per hour. Many of the more 'famous' instructors command a premium price. Be warned if you start taking tango lessons it will seduce and consume your life and you will then be force to make many pilgrimages back to Buenos Aires to dance.
