If you enter Roots Natural Kitchen at 939 W. Grace St. on any given day, chances are it’s bustling with people, from college students in line creating their own salads to delivery drivers grabbing brown paper bags filled with grain bowls. Located in the heart of the Virginia Commonwealth University area, the fast-casual concept with its own ordering app made its Richmond debut three summers ago and has since garnered a faithful following. Originally launched in Charlottesville, Roots was the vision of young business-savvy UVA graduates Alberto Namnum and co-founder Alvaro Anspach.
