If you want to see the unofficial take on contemporary Cuba, go to see the Cuban collection in the Museo Nacional de Bellas Artes, just behind the revolutionary museum.
Artists have consistently been given more freedom of expression in revolutionary Cuba so, apart from seeing some really accomplished contemporary art, you get an idea of what Cubans really think about the revolution, both the positive and the negative.
Calle Trocadero, e/ Zulueta y Ave. de Belgica, Havana, between Parque Central and the revolutionary museum
