Mario's SeafoodB+

7522 N Interstate 35 Frontage Rd Building C, Austin, TX 78752 · Seafood restaurant · St. Johns

Lively Mexican seafood spot with generous portions, frequent specials, and energetic music; great for groups, but noise levels and occasional service inconsistency may frustrate some.

Our take

Mario's Seafood delivers competitive quality with solid food quality anchored by fresh seafood and hearty soups, paired with attentive service that handles the festive, lively dining room well. However, inconsistent execution—particularly with oyster freshness and occasional bland or rubbery dishes—prevents the grade A performance the kitchen shows on its best days. Strong value and genuine community loyalty make this a reliable neighborhood favorite, though not a destination standout.

In more detail

This place hums with festive energy—TVs tuned to soccer, mariachis or karaoke on select nights, and staff who lean into birthdays with big smiles. One diner summed it up: "Service was friendly and quick, and the room felt like a celebration." The scene skews lively rather than hushed, and the space reads colorful and casual. In the kitchen, the approach is Mexican mariscos with Tex-Mex comforts—think hearty molcajetes, rich seafood soups, baked oysters loaded with chorizo and cheese, and fresh ceviches. Food tends to be bold and generous, with specials that make sharing easy. A few guests have hit the occasional miss (a chewy calamari here, a bland aguachile there), but most report satisfying plates at fair prices. Families are welcome. There is a real kids section with $6 mains like chicken tenders, cheeseburgers, and shrimp with fries, plus simple sides and churros. Even picky eaters can land on safe options while seafood fans dive into ceviches and fajitas.
