Mariscos Costa AlegreB+

855 N 13th St, San Jose, CA 95112 · Mexican restaurant, Seafood restaurant · San Jose

Festive Mexican seafood spot with bold flavors, lively vibes, and strong service; creative extras like Mexican-style sushi delight some but not all.

The verdict

Mariscos Costa Alegre delivers solid neighborhood dining with strong food quality anchored by standout molcajetes and fresh seafood preparations, plus attentive, personable service that creates genuine warmth. However, inconsistent execution—scattered reports of wrong orders, occasional bland dishes, and isolated food safety concerns—prevents the higher grade this kitchen's best work deserves. The festive atmosphere and loyal following make it a worthwhile destination for seafood lovers seeking lively, generous fare, though reliability gaps keep it from competing with the area's most dependable establishments.

One caveat: Parking is often tough; plan extra time or rideshare
