In 2006, Dario Wolos was selling tacos out of a converted Volkswagen van in the Mexican beach town Playa del Carmen.

The food truck, called Tacombi, has come a long way since then. Today, it's a fast-casual Mexican restaurant chain with 15 locations across New York, Miami and Washington, D.C. It has $27.5 million in funding from Shake Shack founder Danny Meyer's investment fund, fueling a rapid expansion plan across the U.S. — Shake Shack-style — to 75 total locations by 2026.
