Fodor's Expert Review Mercado San Camilo

This jam-packed collection of shops sells everything from snacks and local produce to clothing and household goods. It's an excellent place geared more to locals than tourists so you can spot rare types of potatoes, sample queso helado (ice cream), or eat chicharrones (deep-fried pork). It's on Calle San Camilo, between Avenidas Peru and Piérola.
