Cesar's Empanadas Truck is a food truck in Williamsburg selling Puerto Rican-style empanadas. Fillings include guava and cheese, chicken and cheese, and beef and cheese, along with vegetarian and vegan options, all in a thin, light fry with generous filling. Empanadas are made fresh on the cart throughout the day, and a bean empanada that is not on hand is made on the spot. Multiple cases of incorrect charges and refused refunds mean you should keep your receipt.
