It was in "a second floor near La Rambla": anarquismoencostarica.blogspot.com/2012/10/centro-germinal.html

The writer José Julián Llaguno Thomas that may be contacted via [aeditoresa at gmail dot com] could shed light:

OK, there are plenty of bars called "La Rambla" in San José, but there may or may not be a match with this one: 6th Street, 8th Avenue, San José. It being single-floor makes me doubt it's the same place, but the picture was allegedly taken in 1962, so the Germinal center may or may not have been demolished by then. facebook.com/groups/286573528941585/posts/917371925861739/
