Sorry Alex, you have great info about BsAs which I always respect, however when it comes to Tango shows, especially the ones like the one at Faena are tango for export and tourists. Not real or even good tango. I have be coming to BsAs since 97 at least twice a year, now dividing my time between ny and BsAs just for this purpose.

As you stated there are many tourist rip off's of tango in and around BsAs and while Faena's is decent I would never consider going to such a show.

There are plenty of real Milongas every night, some good some awful. The scene changes every night. The best thing I can say is that if and when someone wants to attend a milonga email me and I will be happy to see what is doing at what milonga. While a milonga might be good on a Monday it may be awful on Tuesday.

Also most milongas charge 7-12 pesos not the high cost at the shows.

While these are not "shows" many people just go to watch the dancing and there usually is a performance by some professional dancers. As an added bonus there usually is a lesson early in the evening included in the admission.
