"If you ever wondered how and where chefs like Enrique Olvera of Pujol find the rare, organic, regional ingredients that even locals don't know about, it's at this famous delicatessen in off-the-beaten-track Colonia Claveria (though there's a new-ish sister shop in Condesa now, too). Here, Chef Gerardo Vazquez Lugo, the man behind the wonderful Restaurante Nicos, and one of the main representatives for Slow Food in Mexico, sources the best regional products across the country, from Oaxacan cheeses, to foraged mushrooms, ancient grains, dried chilies, and more."
