The Story Behind Round Rock’s Best Mexican Seafood Restaurant: Our Signature Seafood Soups
The Aroma of an Authentic Seafood Dream
If you walk into Unos Mariscos O Que on any given day, there is a specific aroma that greets you. It’s the rich, savory smell of simmering spices, fresh citrus, and the highest quality catch. This is the scent of our Caldos de Mariscos—our signature seafood soups and stews. But for the Fregoso family, that aroma is more than just dinner at a local seafood restaurant; it is the smell of a lifelong dream realized right here in Round Rock, Texas.
A Legacy Born on the Coast
Before we made the journey to Round Rock in 2012, our story began on the coastal waters of Mexico. In Sinaloa, fresh seafood isn’t just a meal; it’s an entire culture. It is where our patriarch discovered his true passion. His deepest dream was never about owning a massive, corporate dining room; it was simply to open an authentic Mexican seafood restaurant and cook Caldos de Mariscos so perfect that people would travel from all over Texas just to take a sip of the broth.
He spent years perfecting the balance of flavors—learning how to draw the sweet richness from gulf shrimp, the savory depth from fresh fish, and how to introduce that signature Sinaloan fiery kick. This wasn’t cooking from a recipe book; it was an education in authentic seafood preparation passed down through generations.
The Art of the Perfect Seafood Dish
What makes a truly unforgettable bowl of seafood soup? At our Round Rock seafood restaurant, we believe it starts with a profound respect for the ingredients. We don’t cut corners. Our broths are slow-simmered for hours to build a complex foundation. We use a proprietary blend of chilies and spices to create that warm, citrusy heat that our coastal cuisine is famous for.
When you order a Caldo here, you are getting the absolute freshest seafood, cooked precisely so it remains tender, never chewy. Whether it’s our hearty Sopa de Camarón (Shrimp Soup) or a complex 7 Mares (7 Seas Seafood Stew), every bowl is made with the same dedication and love that our family brought with us from Mexico.
Comfort, Community, and the Best Seafood in Round Rock
For nearly three years, we have had the absolute honor of serving this incredible community. In that time, our Caldos have become a favorite for anyone craving real, traditional seafood. They are a comfort food for when you are under the weather, a festive centerpiece for a family gathering, and the perfect weekend recovery meal.
If you have been searching for the best seafood restaurant near you, we invite you to come in, grab a table, and try a bowl. When you do, know that you aren’t just eating a great meal; you are helping fulfill a family dream that started with a simple pot of simmering seafood soup decades ago.
