Usera is the neighbourhood Madrid kept overlooking until it became the city's Chinatown — the densest barrio chino in Spain, where supermarkets, bakeries and tea houses turned a working-class quarter south of the river into the best place in the city to eat the food its own restaurants are now copying.
Start in the food streets, where the shopfronts run in two scripts and the menus are hand-lettered for the neighbourhood. Buy an egg tart or a steamed bun, sit with a proper loose-leaf tea if you have time, and let the queues tell you where to stop — the good places shift too fast for a fixed name. The Mercado de Usera shows the change cleanly: Spanish ham stalls and Chinese greengrocers under one municipal roof.
Then walk it off. The Parque de Pradolongo drops south in a long green valley — a boating lake, pine slopes, families picnicking in a dozen languages. Climb the western rise for the view back over the rooftops, follow the park down to the river's southern edge where the city frays into ring roads, and take the metro home from San Fermín-Orcasur.
