If you are in the 'white city' of Arequipa and you would like to get your hand on some authentic food (both raw and cooked), your obvious destination would be the Mercado San Camilo, located right next to the Plaza de Armas.
Be warned though that once inside, the odors can get pretty pungent, especially if you are hovering around the sections that sell meats and fish. However, that is also a sure sign that you've indeed made your way inside an authentic food market.
The market houses underground food courts as well where you can savor many of the local delicacies of Arequipa.Places nearby:
