Mariscos Jalisco (CLOSED)

Raul Ortega has been operating his Mariscos Jalisco truck for more than a decade, longer than most food bloggers have been blogging about loncheros like this one and more than long enough to earn a devoted following. Indeed, you'll queue up with folks from near and far who make this taco pilgrimage. The menu item to order: tacos dorados de camaron ($1.75)—a taco stuffed with fresh, plump shrimp, cleanly fried, doused in a mild salsa and topped with avocado. Claim a spot on the curb and you'll no sooner devour the tasty bite than go right back in line to order another.
