Fondas are one of the most popular places to grab a meal on the go. These small kiosk-type restaurants serve their food from glass boxes heated by a light bulb. Most, if not all of the food served in fondas are fried - rice, hojaldres, pork chunks, empanadas. Fondas also serve a soup called sancocho. Sancocho is a type of chicken soup flavoured with onion and cilantro.
