The sign behind the counter of colorful goodies at Panadería & Pastelería Santa Fe reads "Bienvenido a su panadería," and patrons are made to feel welcome, indeed. Baker/owner Juan Acu?a always has an extra minute to explain his intricate pastries -- sugar-coated conchas, ear-shaped orejas, lemon-flavored flautas, empanadas, cream-stuffed horns -- or discuss in depth the spices he carries, many of which have medicinal properties. A refrigerator case holds other Mexican specialties, including crema and homemade chorizo. And for a really sweet deal, pick up one of Acu?a's tres leches cakes, the most toothsome in town.
