Everyone has a weakness. For some, it's gambling. Sex. Chocolate. For us, it's Azteca's glorious conchas ? swirled sweet rolls laced with a ribbon of sugary pastel icing. It's hard to go into this bakery and come out with less than a sackful of the light, flaky pastries. Founded by Bernardo Lopez in 1956, Azteca is now one of the largest local suppliers of baked goods. The shop has since been passed on to his children, and now employs dozens of bakers, but the high quality of its food has never changed. Regular offerings include fruit-filled empanadas (turnovers), cuernos (croissant-shaped rolls) and orajas (puff pastry). It's not unusual to find customers with their noses literally pressed against the glass display cases, ogling the bolillo rolls and butter cookies inside. Sure, the place serves fabulous cosido, a hearty beef soup with root vegetables and corn, but who can think about lunch when the sweet scent of pan dulce is wafting from the kitchen?
