Oscars Mexican Seafood in Pacific Beach should be your first stop in town for some really good batter-fried or grilled fish tacos. The place is pretty casual, there’s usually a line, and the tacos come with the classic toppings: shredded cabbage, onion, tomato, cilantro, and avocado. Depending on what’s available that day, you can order fresh yellowtail or snapper in a burrito, torta, or plate, but there’s also some great ceviche and shrimp, chorizo, and veggie tacos, too.
