El Califa de León, an unassuming taco joint in Mexico City, measures just 3 metres by 3 metres and has space for only about six people to stand at a squeeze. Locals usually wait for 5 minutes between ordering and picking up their food.
All that changed on Wednesday, however, when it became the first Mexican taco stand ever to win a Michelin star, putting it in the exalted company of fine dining restaurants around the world, and drawing crowds like it has never seen.
