Standing on a sidewalk at 9:30 a.m. in Mexico City, waiting for food, one typically imagines pan dulce (sweet bread), tamales and piping hot atole, a drink made from corn. Yet there we stood waiting for Arroz Black Tiger – a steaming, heaping, fried rice dish with salmon, surimi, shrimp and white mushrooms, something you might find for dinner at a trendy Asian fusion restaurant in Roma or Polanco, but certainly not for 135 pesos (US$7.30) and not at that hour. Nevertheless, business was humming, and several clients rushed in and out to place orders for their office, buying early before ingredients start to run out. Why so early?

Each Mexico City market is a universe unto itself – a bustling hub of neighborhood activity and a feast for the senses that borders on the overwhelming. From food stalls serving up just about any dish from around the Republic to entire city blocks of plants and cut flowers to fresh produce and meat, the many local markets are a can’t-miss stop on every visit to the Mexican capital.

The Robles family has sold tortas in downtown Mexico City for over 70 years, earning generations of devoted customers. But this year could be its last. Their story begins in 1940s Mexico City, at the intersection of Doctor Mora and Juárez Avenue, the southwestern corner of the Alameda Central. Diego Rivera immortalized the famous park, the first of its kind in Mexico City, in a 1947 mural, imagining over 100 seminal figures from Mexican history strolling through the grounds. On a sunny summer morning at Tortas Robles in Centro Histórico, Guadalupe Robles points to a photograph from that same year, 1947. The photo captures her father, Alejandro Robles, leaning over the cart from which he sold tortas.
