    Absolutely fantastic. We had the squid appetizer. I had the monkfish entree and the blueberry tart. The dessert was among the best that I have ever eaten. Not overly sweet, the natural taste of the perfectly ripe berries alongside the delicious tart was incomparable. Both of my adult kids told me that this is the best restaurant they have ever been to (they had the ribeye and the cornish hen). Service was exceptional as well.

    We always eat at Ostra as it is one of our favorite restaurant’s! The service is always great, along with the crispy fried oysters and the branzino my fiancé and I always get and share. You can’t go wrong with anything on the menu.

    Amazing food. Note, we sat at a wing that is near but outside the main seating areas the noise level at the main area is high - it is trendy and chic. If you don’t want it, sit in the wing.

    This was one of our best dining experiences. The cocktails were unique and fresh. All the tartare were amazing. Our wine was one of the best we’ve ever had. Our server was fun and funny. Such. A. Fun. Dinner.

    We are locals and were excited to try Ostra. The service was exceptional from the moment we walked in the door to the time we left hours later. Recommend the Hamachi crudo, paella, and salmon. There was a very minor mix up with our entrees that really was not an issue at all to us, but staff went above and beyond to sort it out and couldn’t have been more apologetic. They comped us a dessert. Phenomenal way to end the dinner. Our server was very attentive the entire evening.

    Pros: Excellent food and nice ambiance to indulge. Cons: Seating is somewhat dense for this restaurant class. Service is inconsistent 10 min until we got to order drinks. By then we had already settled on the appetizers which came within 5 min. We forgot to order sides (here the service could also have helped), instead we had to spent a few minutes to flag somebody down. The Seabass Tatar, though very tasty, was obviously prepared ahead of time, which made the truffle slices on top soggy. Still, all in all, an enjoyable dinner.

    The service was exemplary. We got Crispy Native Oysters, Ricotta Gnocchetti, Risotto, and Broiled Twin Maine Lobster. They were delicious, except Risotto which was a bit too salty for our taste.

    This was my second time dining at Ostra, the first time was two years ago. I’ve since moved to Europe and I flew down back to Boston for the week with one place in mind - Ostra. I’ve been reminiscing over their salt crusted branzino ever since and after two years of waiting, it certainly did not disappoint. The service was impeccable and everything was cooked to perfection. If you are a seafood lover I highly recommend dining here. I’ll definitely be back a third time soon.
