Empanadas can be such a good thing. What could be better than an easy-to-carry pouch full of spiced meat? Sadly, more often then not, they are little pockets of disappointment: ancient, dry things that sit under heat lamps in gas stations. In the old-old country (Spain, not Cuba), they were heavenly. The tradition continues at this market, which churns out fat pies filled with cod, ham, tuna, chorizo, or chicken. Each slice is about the size of a DVD case and three times as thick — it's yours for $3.50. For $23 you can have the whole sheet. Be careful, though: This place has everything fine and Spanish. The chorizo is rich with the smoky flavors of authentic pimentón. The cheese is pricey and delicious. The Serrano is second to none. Even the women are pretty, frank, and funny. Get in, get your empanada, and get out, lest you wind up penniless and love-struck.
