I see references to Mercado La Merced and Mercado San Juan--what are your favorite markets in Mexico DF for chowing? Why? Are they open daily, just week days, or just weekends?
We're really looking for prepared food, since we won't have time or a place to cook. Thanks!
Eat_Nopal did a previous post linking to a government database of 500+ mercados/tianguis, but that's rather too much for me to parse--any specific favorites out there?
