This is the most popular summer milonga on Fridays! It is a kind of melting pot where the during winter separated groups come together. It usually activates also the old milongeros and milongeras who have not been dancing for a while. With other words there is many rejunions!
It is the cheapest one too! A card for period May-September costs about 25 € and you can dance the other days too. The concerts are included as well.
