It was past midnight when we left Alejandro’s paladar. Casa de la Musica had just shut for the night and people – tourists and locals – were walking home en masse.  The way it works, the Cuban hustlers – mostly men – were not allowed to mix with the tourists on the steps of the venue. Instead, they waited at the bottom, held back by the local police. But once Casa de la Musica closed, there weren’t enough police to keep all the hustlers in check.
