Fodor's Expert Review Dulcería de Celaya
It was founded in 1874 and has been a haven for those with a sweet tooth ever since. It specializes in candied pineapple, guava, and other exotic fruits; almond paste; candied walnut rolls; and cajeta, made with thick caramelized milk. These traditional sweets are not available in many other stores in Mexico City. There's another branch in La Roma.
