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.

    Ostra gets all of the essentials right - creative cuisine, superb service, comfortable dining space and great location. We are always happy to secure a reservation at this very popular restaurant. We began with perfectly made cocktails (they also have an extensive wine list) followed by first courses of grilled octopus and mushroom risotto. The main courses were Faroe Island Salmon and grilled Bronzino - both amazing. For desert we shared panna cotta. Our waiter was professional, personable and knowledgable assisting with meal choices. The front of the house staff was also accommodating and welcoming. One of our favorite places for dinner for two or more.

    This was my second time dining at Ostra and it will not be my last! I was with my mother to celebrate her birthday with a quick dinner before seeing a show nearby. Everyone on the staff made us feel like celebrities! The service was amazing and the food was the highlight! We enjoyed a dozen of the most delicious freshly shucked oysters I’ve ever had outside my own home. Not wanting to be too full while sitting through a show, we shared the ricotta gnocchetti first course and the grilled Faroe Islands salmon entrée. Both were delicious and the kitchen took the time to individually plate our portions. It was truly first class! They were so sweet to recognize my mother‘s birthday with a delectable scoop of vanilla ice cream and a delicious meringue hidden at the bottom. We wish we could have lingered over dinner longer, but we certainly will on our next visit! Do not miss this Boston gem with its stunning dining room and en vogue ambience.
