After a long day on a fluorescent boat at Xochimilco, the vestigial canal system just south of Mexico City, we stopped by the famous "El Lago de los Cisnes" in Chapultepec for tacos. Tired and sunburned, we wanted something quick and satisfying. Mexico City, as it turns out, has the perfect solution: tacos al pastor. The restaurant seemed to combine the flavor of street food without the street; it was a comfortable sit-down place. Despite the pork rotisserie and roaring fire pit by the door, the ambience inside was quiet and tranquil full of tables able to accomodate large groups of people. Our waiter served as the mediator between the chaos and the calm.
