Oysters appear in the ceviche mix alongside shrimp, octopus, calamari, crab, clams, and scallops, dressed simply with tomato, onions, and cilantro. This preparation draws from Tijuana-style seafood traditions, emphasizing fresh, briny seafood combined rather than served solo on the half shell. The oysters contribute a subtle chew and sea flavor that balances the other proteins in the chilled dish. Diners note the portion sizes allow for sharing, with small, medium, and large options available.
