One of the Front Range’s most well-known full-service Mexican food restaurants is preparing to serve diners in Denver for the first time in its 22-year history. Los Dos Potrillos announced plans for its seventh location at 4100 E. Mexico Ave., Suite G in south Denver. It’s expected to debut early next year. The family-owned company, which opened its first eatery in Centennial in 2002, specializes in dishes like fajitas, burritos and tacos, and it’s become a local favorite.
