Fodor's Expert Review Mercado Hidalgo

It's a 10- or 15-minute walk from Jardín de la Union to see this 1910 structure of pink quarry stone, cast iron, and glass, designed by the one-and-only Gustave Eiffel.

T-shirts and cheap plastic toys fill the balcony stalls, but the lower level is full of fresh produce, hot food, and colorful basketry, as well as peanuts and regional candies (some shaped like mummies).
