Las Tortas

Had Steve Ells found his inspiration for Chipotle in Guadalajara rather than San Francisco's Mission District, the result might have been Las Tortas. Instead, this awesome spot is the brainchild of Guillermo Campillo and Tymen Schrueder (of Rincon del Sol in Boulder), and it sells nothing but tortas -- about two dozen varieties, from the simplest Jalisco, sporting nothing but steak and chicken, to the most bizarrely overpowering La Macha, topped steak Milanesa, chorizo, chile, a fried egg and a hot dog, all crammed onto a telera roll (just try calling a sandwich made with anything other than the famed Mexican bread a "torta" and watch the fireworks).
