Our Story

From the Pacific Coast to Round Rock

What makes Sinaloa-style seafood different? It's the perfect balance of fresh-caught quality, vibrant citrus curing, and that signature fiery kick you won't find anywhere else.

We are the Fregoso family. Our father, a passionate cook, grew up making caldos de mariscos in Mexico and dreamed his whole life of opening his own restaurant. When we moved to Round Rock in 2012, we made that dream real — a place that feels like home, with live music on the weekends and flavors that speak to our roots.

Frequently Asked Questions

Where can I find authentic Sinaloa-style seafood in Round Rock?

Right here! We proudly bring coastal Sinaloa seafood to the heart of Round Rock at 1350 E Palm Valley Blvd, Round Rock, TX 78664.

What makes Sinaloan seafood different?

Bold, incredibly fresh flavor. Instead of heavily fried plates, we specialize in crisp, lime-cured dishes like aguachiles and ceviches, packed with fresh chilies, cucumber and red onion for a refreshing kick.

What should I order on my first visit?

You can't leave without trying our famous Torre de Mariscos — a towering stack of lime-cured shrimp, octopus and tuna in our signature salsa negra. If you love heat, the Aguachile is a must.

Do you offer delivery?

Absolutely. Tap the "Order Delivery" button at the top of the page and enjoy the best mariscos in Texas from your couch.

Is the aguachile spicy?

Authentic Sinaloan aguachile brings the heat — fresh crushed green chilies give it that signature coastal kick. But everything is made to order, so just ask for a milder version if you prefer.
