A family business is doubling its footprint in north Denver next year as it adds another kitchen and storefront for its sought-after tamales and tortillas. Pochitos Tortilla Factory, 4421 Tejon St., will expand into another building less than a mile east at 4200 Jason St., owner Levi Luna said. He plans to start renovating next month and open up for to-go sales in March. Pochitos Tortilla Factory in Denver plans to open a second location nearby.
