Yelp
The biggest market in Mexico City and the biggest market I ever been in. Get ready to get a workout cause you can walk 5 miles in and you haven't even scratch the surface of this market.
The main and only reason to come is the food! tacos, soups, Gorditas, cut season fruit, and michelada. You can look around for the best food stand to eat but that'll take you forever, just go with your gut and try it.
