Mariscos La Costa

Mariscos La Costa sits right on International Boulevard in Oakland, serving up a casual, no-frills seafood experience that reflects the city's diverse Mexican-American food scene. This spot works well for a quick bite or a laid-back lunch, especially if you’re into fresh ceviches and traditional seafood cocktails. The ordering setup is straightforward, with a walk-up window and outdoor seating that leans into a fast food or casual fast-casual vibe rather than formal dining.

Seafood takes center stage here, with highlights like the Super Campechana, ceviche tostadas featuring shrimp, crab, and octopus, plus Aguachile and shrimp cocktails that lean more toward rich, saucy presentations than the ultra-tart style some might expect. Carnitas tacos and burritos also appear on the menu, broadening appeal beyond just seafood lovers. Bring your own cerveza or beer if you’d like—the staff don’t mind and that adds to the informal, friendly atmosphere.

The place buzzes with regulars during lunchtime hours, drawn by the speedy service and satisfying, well-portioned plates. The seating is primarily outdoors, so it’s best visited on mild or sunny days, when you can enjoy the open-air setting amidst the hum of International Blvd. Parking can be tricky during peak times, reflecting its popularity among local office workers and neighborhood residents grabbing a quick, flavorful meal.

Visitors looking for a straightforward seafood fix with pared-down presentation and bold flavors will do well here. It won’t feel like a white-tablecloth event — what you get instead is solid, fresh Mexican-style seafood with a local, approachable touch, all in a casual environment where speed and taste come first.
