One of Mumbai’s miracles is Mumbai’s Dabbawallahs —a community of 5000 dabba (lunchbox) deliverymen. It is a hereditary profession. Every morning the Dabbawallahs deliver hot meals from the kitchens of housewives to the offices of their husbands, and then return the empty lunchboxes back to the homes in the afternoon. For 120 years they have provided Mumbaikars with a taste of home in the office. They navigate through the overcrowded local trains and chaotic streets—that often have a namesake or more than one name. The Dabbahwallahs are illiterate, and instead rely on a complex coding system of colors and symbols to deliver dabbas in the labyrinth that is Mumbai. Harvard University analyzed their delivery system, concluding that just 1 in 8 million lunchboxes is ever delivered to the wrong address. The Lunchbox is the story of that one lunchbox.
