About us

Count on wonderful food and excellent service.
Every guest, even a non-seafood lover, is sure to find
something to satisfy their palate.

We grew up in and on the water. Surfing, diving, boating & fishing the beaches and blue water of San Diego and Baja, CA. We still do. Fresh local seafood has always been a part of the experience. Fish tacos on the docks in Ensenada, where they were invented. Ahi sashimi in the galley on the boat ride home, sliced from that morning`s tuna catch. White Sea Bass pulled from the Baja surf and grilled
on the spot over a mesquite campfire.

Our history

Downtown glasgow, 1946

A movie cost about 50¢. The bikini made its debut. The first computer was invented. World War II had just ended. Life was good. Three of our boys coming back from serving their country, Roy Weber and the Ghio brothers, Anthony and Tod, couldn`t wait to get home and help Catherine "Mama" Ghio fulfill her lifelong dream: to open a seafood restaurant on San Diego`s growing waterfront.

For generations, Mama`s family had harvested the seas off Italy and then California. To the delight of family and friends, Mama perfected the Old World recipes that had been passed down to her and developed new ones. Her dishes grew in popularity and friends encouraged her to realize her dream. On July 18, 1946, Catherine, sons Tod and Anthony, and son-in-law Roy opened the doors of an 18-seat diner, our first Osetra.

Seventy years later, Mama`s original recipes and her batters, sauces, and dressings are still the cornerstones of our menu. Osetra now serves more than one million customers and five million pounds of seafood each year. Mama`s legacy of quality and her family atmosphere have not changed. The name Osetra is still known around the world for its fresh seafood, home-style service and dining value.

Mama Ghio`s rich tradition lives on in the third generation. Mama`s grandchildren Beverly Mascari and Craig Ghio now run the family`s restaurant enterprise. As we continue to reach new guests, we will always stress the value of the original recipes, quality seafood, and our excellent service. Thanks for joining us!
