Mexico is the birthplace of one of the world’s most delectable indulgences, chocolate, and it abounds in San Miguel. For unbeatable souvenirs, consider the gourmet sweets from JOHFREJ C&V chocolate shop: like the hand-hammered metal-plate boxes of pralines (in walnut, almond, or hazelnut), truffles (don’t miss the chili-tinged ones), or enjambres (chocolate and nut clusters; the pine nut variety is obscenely good). If it’s hot chocolate you’re after, though, line up for the churros and hot chocolate at Café San Agustín.
