From Seafood Tacos to Hearty Menudo, We Serve Flavor You’ll Crave

Seafood, Tacos, and More

Mary’scos Restaurant brings 20 years of experience to every plate we prepare for families across Corona, CA, and that experience shows up in every dish we serve. We started with a simple idea: serve fresh seafood and honest Mexican cooking in a room where everyone feels welcome, from grandparents to little ones. That idea still guides how we run the kitchen and greet guests at the door today.

Our menu leans on the coast and the recipes we grew up with. We make bright, citrusy ceviche and pile our seafood tacos with fresh fish, and we pour aguachile for the folks who like it spicy. When the weather cools, our menudo and seafood soup do the heavy lifting, and our chilled seafood cocktails stay popular all year. On the raw side, we serve oysters that let the seafood speak for itself, and we keep a good selection of aguas frescas, beer, and other beverages behind the bar.

We did not forget the younger guests. Kids can order chicken tenders or burgers while the grown-ups work through a plate of botanas and a cold drink. We offer dine-in service for the full experience, takeout when you are short on time, and we happily take reservations for larger groups and celebrations. Walk-in customers are always welcome, and there is parking available right here, so getting to us is easy.

Beyond the dining room, we cater weddings, office lunches, and family gatherings, with menus that reach beyond our Mexican and seafood roots into Italian, American, and more. Whatever the occasion, we cook it the way we would cook for our own table. Visit our restaurant today.
