Located in Barrio Manrique, Casa Gardeliana was Medellín's main tango venue for years, hosting tango bands and dance shows. It still holds events occasionally but is now basically a small tango museum. On the last Friday of the month, the casa hosts the 'Gran Fiesta Tangera' (6pm to 9:30pm) with Argentine empanadas, wine and plenty of dancing. Reserve a table.
It's possible to organize private dance classes here (COP$80,000, 90 minutes) – the price is the same for one dancer or many, so get a group together.
