I was thinking about buying chocolate in a bar or something and breaking it up as chocolate chunks rather than chips, but i did find them in Plaza Vea of Jesus Maria. Metro of Jesus Maria had them as well. It is a generic peruvian brand called negusa. Comes in a beige and brown package, quite a bit smaller than a bag of chocolate chips in the states. The package says, Gotas sabor a chocolate, which makes it sound like its not actually made of chocolate but the ingredients do include natural cocoa powder so hope they made descent chocolate chip cookies. They are definitely miniature sized, although isn't everything compared to the U.S.
