Great for fine wines

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.

This is my second time here, and O Sea still hasn’t missed. We had a small inconvenience when it came to our squash salad but both the servers and management accommodated us incredibly well. I cannot wait to dine here for a 3rd time!
