"Watch real-life tango at a milonga There are two ways to see tango in Buenos Aires : at a glitzy made-for-tourists tango show (which is, to be fair, a good time in its own right) or at a milonga, or tango club. One of the best, El Niño Bien, well off the tourist circuit at the Centro Región Leonesa, closed its doors in 2013, though local tango enthusiasts hope for a reopening of the legendary venue. In the meantime, seek out alternatives like La Catedral, El Beso, or the milonga at La Confitería Ideal, by checking the online schedule called 'Hoy Milonga.' Even if you don't dance, you can sit at a table on the side of the dance floor, order a bottle of wine, and watch the locals in action — but be prepared for the fact that you'll almost certainly be asked to dance at some point in the evening."
