Best churros and hot (and cold) chocolates in the city. Owned by Margarita Gralia (I'd never heard of her either), and she's put pictures of herself and Antonio Banderas all over the place. There's often quite a line to get in, but you can always grab churros and chocolate to go. It's a very popular late-night place for Mexicans. Also try the corn empanadas.
