Tango Shows

If you are willing to go to a tango show I recommend you to go to a theatre or a cultural centre.
Check Centro Cultural Borges webpage and look for tango shows in "espectaculos".
http://www.ccborges.org.ar/ I highly recommend them. In Feb 2008 the price was 35 pesos.
The Centro Cultural Borges is inside of Galerias Pacifico, at the 1st floor. This Gallery is also worth seeing for their paintings.
Galerias Pacifico address: Viamonte St. 500 (between Florida St. and San Martin St.)

You will be offered shows in other places where you can get dinner also. They are very touristy, therefore they are very expensive. Prices are from 150 to 300 pesos.
