How about calle Lavalle? Blocks and blocks of movie theaters, with some huge ones in Corrientes and Cerrito. There must have been close to thirty cinemas and theaters in a three block radius. It was exciting to go downtown to the movies on Saturday nights. There were some suburban movies theaters, too, but nothing beat the excitement of going to Lavalle.
True but Lavalle had been going downhill for many years. I remember many years ago the cinemas were still decent. There was a place you could go to see all the many films listed with hours of screenings. I think just about everything is gone now. At least one major cinema is now an evangelical Protestant church. Not much left in the way of restaurants. Two decent ones the last I looked - La Estancia and Palacio de las Papas Fritas. They may not emerge from the crisis (or did Palacio close before the crisis?). Also Calle Florida used to be MUCH nicer. Before globalization and the internet, there was much more character to Buenos Aires. Its was a much more social city. People interacted a lot more. Now everybody's on his phone 24/7 and watching Netflix at home. Even before the virus, BA had become a far more isolated society, far less social and much less Argentine in the positive sense.
