Our Story

Born by the Sea,
Raised on Flavor

Mariscos Altamar started with a simple belief: the best seafood tastes like it came straight from the water. Our family has been perfecting Mexican seafood recipes for over three generations, and we bring that same passion to every plate in San Antonio.

Whether you're craving a cold ceviche on a warm afternoon or a steaming plate of camarones al ajillo with the family, we make every order like it's for our own table. That's the Altamar promise.
