Paco Ponce makes the best paella in Mexico City. (At least I think he does.) Usually he makes it for private parties, for groups of 20 or more people. But periodically he cooks it at a small restaurant in Colonia Roma called La Chicha, at Orizaba 171, almost at the corner of San Luís Potosí. Don't miss your chance this Saturday the 8th, from about 2 pm. That's him in the foreground, next to the pan. I haven't a clue as to who's talking on the telephone.
