The Condesa area is sort of like the east village, full of bars and restaurants. I'd recommend eating in Azul Condesa (modern mexican), and I would definitely visit El Califa, which is a classic Taqueria where you’ll have the greatest tacos in the city.
mexicanfoodporn: Tlacoyos - Tlacoyos are corn “cakes” (thicker than a tortilla) they are stuffed with beans or chicharrón. But then can be topped with chorizo, crema, salsa, cheese and many other “guisos”. Photo: hannah_y_juan
