Friday or Saturday: Livraria Megafuna (ed. Copan)
Any afternoon or night: Cineclubes. There are also Belas Artes and Reserva Cultural but I am not that attracted by their programming. I wish for Cine Bijou and Teatro Oficina.
Oficinas culturais. There is a lot of theatre and other cool stuff.
Livraria Tapera Tapera
Pinacoteca and note, it is moving
MAC and Museu Afro-Brasil
SESC activities including program of cinema retrospective — a good reference for films
