After two years of operations, the owners of The Berlin Cafe changed gears in the winter and reopened March 11 as Dos Amigos Cantina at 2552 Stonebrook Parkway, Ste. 300, Frisco. Dos Amigos prepares all dishes and drinks using fresh ingredients. The cantina offers queso, guacamole, quesadillas, fajitas, margaritas and other Tex-Mex delights.
