San Diegans are relentless in their pursuit of the perfect fish taco, so trust the well-worn path to this ultra-casual, no-frills counter-serve joint. All the seafood—ahi tuna, mahi mahi, shark, soft shell crab—is super-fresh, made to order with your choice of sauces (mmm, lemon-garlic butter), then slapped on a taco, sandwich, salad, or plate. Other winners include the homemade New England-style clam chowder, jumbo shrimp cocktail, and oysters on the half shell. There's also a kids' menu and a local IPA on tap. There's only one register, so lines can get long; try weekday afternoons to avoid the onslaught.
