As San Francisco continues to get more and more gentrified and expensive, it's good to know places like this hole in the wall still exist. This place is basically a corner market that has a built in lunch counter. So you can buy some package beer, pull up a seat at the lunch counter for one of the massive (and cheap) tortas they cook up on site. The highlight? The greasy, decadent Cubana (Cuban pork roast sandwich).
