Beware some of the tango shows in Buenos Aires that are recommended by your hotel. Bar Sur in San Telmo and Mandera Tango in the port area of BA are a rip off and are tourist traps.
For example, they will try and give you a poor seat with a bad view for you to upgrade to the 'VIP' area. They include a poor dinner with horrible house wine then con you to have a photo taken with two of the tango dancers who they say appear in the show then you never see them again.
They'll also offer you a cocktail for 40 pesos which is three times the price of any cocktail anywhere else. Bar Sur charges 210 pesos per person for the dinner and show in one of the tightest floor spaces in BA. Then the drinks are double the price of anywhere else in BA. If you want to see tango choose very carefully.
