Chocolatería San Ginés has been feeding Madrid since 1894. It's tucked into the Pasadizo de San Ginés, an alley so narrow that most people walk straight past it. The red neon sign is the only clue.

The menu has never changed: churros, fried fresh, and chocolate so thick a spoon almost stands in it. On an ordinary day, the kitchen turns out four thousand churros. The place runs twenty-four hours. Post-theatre crowds, teenagers stumbling from nearby clubs, mass-goers from the church next door: all end up here.

Where churros came from is contested. Portuguese sailors may have carried the idea from China; Spanish shepherds may have invented them in the mountains. Hernán Cortés returned from the Americas with cacao, and the pairing has never been improved upon.

VoiceMap's tours trace churros' improbable origins across continents, connecting San Ginés to the food culture and city it has nourished for over a century.
