There's pig paraphernalia everywhere in this fixture on the 18th Street strip, from pictures and sculptures to coin banks and comic strips. A large pan of fork-tender shredded pork is a main attraction, second only to a high stack of chicharrones (fried pork rinds) under the heat lamp. The few tables are packed every morning, and they do a brisk trade in takeout. The limited selection includes carnitas (soft corn tortillas wrapped around shredded pork) and menudo; there are also fresh nopales and taquitos de sesos,brain taquitos. The only question you're asked upon sitting down is "how many," referring to the carnitas, served in plastic baskets. Sneak a peek into the kitchen, and you may get a glimpse of a man stirring three huge vats of bubbling pig parts with a big wooden paddle.
