Oh how i wish you didnt post this.. Somethings are better left quiet.
Tourists usually end up in the "tango shows" which are not real at all. Those shows are Tango for export or tango fantasia..
Oth, if anyone needs info on Canning or other milongas let me know. I spend lots of time in them....
In addition to size, age is meaningless, and the milongas get good around 3-4am, Hope there was a good performance the night you were there..
