4. BBQ Combo at Chacarero
While Mexico still reigns as the premier purveyors of handheld Latin lunch food, this Chilean sandwich shop offers something more complex and balanced than yet another burrito. Their signature BBQ combo features slow-cooked chicken and beef piled high on their soft, buttery homemade Hurtado bread, finished off with green beans, avocado spread, tomato, Muenster cheese and hot sauce.
