San Pedro Fish Market and Restaurant • 1956

This fourth-generation family seafood empire on San Pedro's working waterfront serves its World Famous Shrimp Tray—mountains of seasoned grilled shrimp piled with potatoes, peppers, onions, and garlic bread on cafeteria-style trays meant for hands-on feasting. Founded in 1956 by Mackey Ungaro as Vista Seafood and rebuilt on the harbor in 1982, it grew from a tiny 200-square-foot corner store into a sprawling 3,000-seat operation that once did $30 million annually and earned four Guinness World Records. The signature secret seasoning, developed when the fish market transformed into a full restaurant, draws over 20,000 guests weekly who come to sit harborside and dive into messy, utensil-free seafood mountains that have made it one of the most Instagrammed restaurants in America.
