At this no-frills eatery on 16th Street (part of a family-owned mini-chain) you can choose from around 20 varieties of the popular, monster-size Mexican sandwich, each for about five or six bucks. Stuffed with meat, thick slices of avocado, pickled jalapeños, lettuce, tomato, and mayo on soft, round telera bread, we like the milanesa de pollo (breaded chicken), Cubana (piled with ham, pork, and cheese), and the packs-a-punch cochinita featuring slow-cooked pulled pork simmered with achiote, orange juice, and spices. Delicious.
