Situated in Boston's vibrant Back Bay neighborhood, One Charles Street South is home to a modern Mediterranean eatery known as Ostra. Led by Chef/Owner Jamie Mammano and Executive Chef Mitchell Randall, our restaurant draws inspiration from the abundant seafood offerings of both local New England waters and the coastal regions of Europe. With a strong emphasis on specialty seafood sourced from the Mediterranean and various parts of the United States, our culinary creations showcase the natural essence and delightful flavors of each dish through their light preparation.

Review summary

AI-generated from verified diner reviews
Ostra offers a sublime dining experience with "impeccable service," "delicious food," and a "romantic ambiance." Signature dishes like the gnocchetti with lobster and branzino consistently impress. While prices are on the higher side, the quality and thoughtful touches make it a "special celebration" destination. Highly recommended for seafood lovers.

    Exceptional venue. Great food, impeccable service, wonderful ambience. I had a sea bream, which is my favorite fish and is a rare beast in New England. My husband had a zebrano fish. Both were cooked and seasoned to perfection. Plus scrumptious, tender shishito peppers are to die for. Great wine list too. Restaurant exceeded our expectation!

    I prefer sitting in the bar area. It’s quiet and nicely lit (not too bright and not too dark). Service and food are always excellent, as are the cocktails. We have come several times and will continue to be return patrons. Ostra is on my list as a standout in Boston!
