What did the front of the cafe look like? Did the owner give you a reason why it was blocked?
I didn´t talk to the owner, as my Spanish is very poor. The booths use records (old LP´s) as decoration seperating the workstations. The front door was unremarkable, just glass with the usual Ïnternet, Chat, and words like that painted on the glass. I´ll try to spot it again before I leave and see what the exact address is.
I tried to get a screenshot, but it pops up with a ¨Forbidden¨message for about 2 seconds then it closes the browser and the message goes away too fast to catch. But, I can get FreeRepublic everywhere else I try, so it seems to be the exception rather than the rule. Maybe there was some bad word it spotted to trigger that.
