About

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.
