The sun pours through the smokey windows of this upstairs diner and is intercepted by half a dozen coconut palms, casting exotic shadows on the terrazzo floor. Everything – and I mean everything – is a shade of brown, as it has been since its last refurb a few decades ago.

Vallecas is a working-class neighbourhood with an unstoppable fire in its belly. It emerged out of a slum, only to be beaten back to the bones again by the most brutal pummelling the Spanish Civil War could give. Since then, this hard-left barrio has become a close-knit community and home to thousands of immigrants from all around the world, making it one of the most mesmerising corners of Madrid.
