Tooling around Highland Park last weekend, I passed a park at Figueroa and Woodbury(??) where there were three taco trucks parked. One of them billed itself as having "mariscos estilo D.F." Unfortunately we'd just had brunch and weren't inclined to top off our French toast with a taco. (Pathetic, I know.) All I know of Mexico City-style street food is the potato taco. Anyone know how the mariscos might be different?
