O SEA — a seafood restaurant of time and place in the historic Plaza district of Old Towne Orange, recently recognized by the Los Angeles Times as the Best Seafood Restaurant in Orange County and by Wine Spectator Magazine with an Award of Excellence. Something fun, something different, something fresh — O SEA is where seafood is headed. Think salmon ceviche in coconut leche de tigre, tuna poke in gochujang dressing, crispy oaxacan hot shrimp, west coast oysters on the half with thai red curry and tajin’d lime.

Responsibly-procured, best-in-class products, served consistently and at a value, with deeply craveable and seasonal flavors — welcome to O SEA.

We can’t wait to serve you.

We had a wonderful and tasty meal of seven fishes with wine pairings. Each fish item was the freshest and tastiest I have had and we buy our home fish from Santa Monica Seafood which is excellent but not as good as O Sea! My wife and I also did the wine pairings and enjoyed each wine and was relieved that none were too large. I apologized to Mike that we have not visited O Sea since last Christmas! Our New Years Resolution is to visit more often! Maybe O Sea could have more fish themed dinners like the opening day of trout season in CA…the first Saturday in April.

This restaurant is consistently good. We can depend on a delicious meal here. We went early to dine and the service was excellent. We were met by a woman who greeted us with joy, which is always a good start. The menu is easy to follow, and it seems we gravitate to our favorites. Him - Fish & Chips. O Sea makes the most delicious French Fries. I had the Black Cod with Sweet Potatoes, but not ordinary SP, these were bathed in a delicious sauce with layers of flavor. Perfect for swathing a few French Fries through. Divine!
