    Walking in you were immediately welcomed by staff who are polite and professional. your jacket is checked, if you wish, and you are led to your table (assuming you have a reservation or a table is open). the tables are clean and already set neatly and service is provided almost instantaneously. All staff were professional and accommodating. They were knowledgeable on the options and could guide you based on your preferences. the food was amazing and well worth the price. We originally went due to being recommended for paella but every bite and sip we had was amazing.

    Great restaurant. We were well received, the food was very good quality and perfectly prepared. We had the Octopus and Kale salad for starters, salted branzino & filets for main, and melted chocolate for dessert.... everything was excellent. We gave one notch less for the service attention, but perhaps the loud needy table next to us was to blame. We will return given the chance.

    Delicious food and great presentation. We split 3 plates and the first 2 came already separated for us. It was delicious, the atmosphere was beautiful (chandeliers are hand blown glass, not fabric) just all in all a wonderful night and worth the cost. Smoked salmon tartare, gnochetti and paella are top notch as well as the beverages and affogato dessert.

    We have selected restaurants while in Boston based on the ratings. So when we were looking for a fish place we selected Ostra. The ratings were spot on. Food was delicious! We started with the gnocchi with lobster, filled by the Branzino fish. Dessert was the chocolate cake and panna cotta. Service was perfect. Constant touch points to see if we were enjoying our experience. Highly recommended you visit this place.
