Top meal in Boston during our visit. Reservation was easy to get/modify. Ambiance was on point. Yummy drinks and food. One thing I especially like about this place is that they split the appetizer dishes into two for my husband and I...so we didn't have to cut everything in half as we share the appetizers (specially octopus and fish tartar--both were excellent).

What a spectacular gem! We decided on Ostra before seeing a concert in Boston and it was fantastic! The decor and the service was stellar! The gin martinis we ordered were STRONG and did not disappoint! We shared three items: the arugula salad which was scrumptious. the seafood risotto which was the star of the evening and so flavorful and the seafood paella which I found very yummy but my husband wasn't much of a fan (minus one star) and then we had fun dessert that escapes me now but I know it had cotton candy on top! Every time we got up from the table a sever would fashion our napkin into various shapes! I would definitely come back! It's $$$$ but worth it!!!

Ate here again, 7 years later. What an Excellent dinner. Not cheap by any means, but service was top notch and the food/wine/cocktails were all delicious. I would not be surprised if this place is handed a Michelin star in the future. Go here for a special occasion - you will not be disappointed.

The service was incredible. It was like we had one waiter assigned just to our table. He was always there when we needed him. We had the twin lobsters which we served in a hot pot. They were completely shelled so we never had to touch a cracker. The gave us two types of butter; one was seasoned while the other was just melted. The ambiance of the restaurant was top notch. If I ever had the chance, I would return without thinking twice. This was a place to keep in mind if I ever return to Boston.

The restaurant would be five stars if it wasn't for a bit of confusion with the wait staff. There were almost too many people waiting on our table, and it cost confusion as to what we had already ordered. The restaurant was extremely modern. Everything was white and marble, the most notable dish for me was the monkfish, which was extremely flaky and cooked perfectly.

What an experience... excellent service, taste, preparation and vibe! This place is a winner! Lovely wine list to boot...

After a thorough search for a high end Boston seafood specialist, we made our way to the back bay. Ostra completely delivers! The space is contemporary and spacious. There is a nice size bar/lounge area and an adjacent dining room, divided by the giant fish on ice display which is a nice touch. There is also a private room behind the bar area and on this night, there was an event going on so the place overall was hopping. We started with the hamachi crudo and grilled Spanish octopus. The kitchen, without prompting, split the octopus appetizer in two so we could share the dish. That was a lovely surprise. Both were incredibly tasty. The octopus was perfection, tender with a nice delicate char. The crudo was simply gorgeous and tasted as good as it looked. I had the monkfish saddle which was recommended by our server. To be honest, I was skeptical because this poor man's lobster is often overhyped and chewy. Tonight, though, I was blown away. The fish was cooked to perfection and floating in a scrumptious pool of mixed mushrooms and scallions. Although the menu describes a mushroom ragout, I would say it is an exquisite mushroom broth. Hubby had the grilled sea bream which was also delicious. In need of some greens, we did the broccolini with pine nuts along with the leafy greens and garlic. The veggie sides were really a highlight. And though the dessert menu looked enticing, we were sufficiently full and opted out. Two chilled caramel truffles arrived with our check and we devoured them. Ostra will not disappoint. The food and service are top notch. It's not inexpensive, but fabulous seafood never is. So glad my fellow yelpers helped me out in choosing this winner.

Came here to celebrate my bf's birthday and it definitely did not disappoint! Our reservation was at 7:45pm and right when we walked in we were seated right away at a nice booth. The entire night our server was friendly and always came back to check on us. Our tables were cleaned in between dishes with a bread scraper. Even though we were one of the last 2 parties in the restaurant to leave, we were never rushed and they let us take our time finishing our food and desserts. For appetizers we ordered the oysters, calamari, and Alaskan king crab tortellini. You MUST get the king crab tortellini, it was probably one of the best things I've eaten that night. For entrees I ordered the seafood paella and my bf ordered the salmon. The paella came packed with big pieces of seafood and the salmon was perfectly cooked. We both were so full from the appetizers that we took most of our entrees back home. For dessert we had a chocolate mouse with kettle corn and marshmallow. It was a perfect ending to an awesome dinner. Everything we ate you could tell it was freshly made and they cared about the quality of the food. Definitely will be back!
