Mariscos La Reyna del Sur in Chula Vista is a women-owned Mexican seafood restaurant on the Broadway corridor, built on a menu of raw-bar preparations, charbroiled shellfish, and whole-fish plates served from what was formerly the Clamatos y Cocos location. The kitchen sources whole fish and shell-on shrimp from regional purveyors in the same supply network that stocks T & M Seafood, ensuring same-day freshness for preparations including the signature Tostada La Reyna and the botana aguachile platter sized for two to three diners. Fresh-shucked oysters arrive by the half-dozen and full-dozen, available raw or roasted with pico de gallo and melted cheese, alongside cucarachas—split-shell langoustines grilled with garlic butter. The catering arm handles off-site events through the same taquiza-style service model used by Taquizas Los Chuchys, with portable seafood stations for private parties and corporate gatherings. The signature campechana grande layers octopus, shrimp, scallops, clam, oyster, and calamari in a 24-ounce goblet with house-made clámato base, habanero salsa negra, and fresh lime.
