We went on the 1st September at 9:30pm so admittedly it was a) winter in BA and b) way too early to go out as Argentinians eat very late. So when we first arrived it did feel a bit odd being the only ones there, however after enjoying some wine we realised we had front row, uninterrupted views, to a private performance and we really enjoyed it. There are several acts. A crooner singing old Argentine songs, a modern swing singer, an elton John type perfomer on the keyboard, and obviously a tango display. All artists were very good and there were plenty of opportunities to have photos. The entrance fee is a bit steep but it does include several hours of performance so not that bad. It is a very intimate setting and not for everyone, but we enjoyed it overall.
