This was our second Valentine’s Day at Ostra and at this point it might just be a yearly tradition. The vibe is exactly what you want for the night. Dim lighting, candles everywhere, lively but still intimate enough to enjoy your conversation. It feels special without being over the top. We started with oysters which were super fresh and a great way to kick things off. The Chestnut Cavatelli with braised wagyu beef cheeks was the highlight of the meal. Rich, comforting, and the kind of pasta you don’t want to share. We also grabbed shishito peppers in between courses which worked perfectly as a palate reset. Steak came out cooked perfectly and the plate felt thoughtful without trying too hard. Nothing overly complicated, just really well executed food. Service was smooth and paced well

⭐⭐⭐⭐⭐ Outstanding Food, Exceptional Leadership The food at OSTRA was truly delicious. The Boston lobster for $135 was absolutely worth it — so much sweet, generous meat. But the real surprise star was the gnocchi with truffle — rich, aromatic, and perfectly executed. Service was excellent, especially from JJ (Juan), who took great care of us throughout the meal. What really impressed me, however, was Trevor. He came over personally to congratulate us on our honeymoon and surprised us with a complimentary dessert. Later, I noticed he was doing the same for many other tables — greeting guests, making everyone feel welcome, helping serve, and even pouring wine himself. That level of hands-on involvement says a lot. When I asked JJ, I learned Trevor is actually the General Manager. That wa

We made a reservation after an event at Wang Theater. We ordered Grilled Spanish Octopus - $32 (Lemon, Olive Oil, Crispy Salt Capers, Raw Sweet Vidalias). It was very good and fresh. We had a Tagliatelle with white truffle $100. It was delicious - but the serving size is too small for the price. We also ordered the Salt Crust Branzino $150 (Extra Virgin Olive Oil, Lemon, Snipped Herbs, Seasonal Accompaniments For Two… Please Allow 50 minutes). Mushroom and seasonal veggies. The fish was excellent, but the lemon flavor overpowered the flavor of the branzino fish. Regardless, it was very good! The bread was warm and delicious. Overall Rating: 5 Environment: Very clean, inviting, quiet We highly recommend it! Make a reservation because it gets busy. All staff members were excellent

★★★★★ 5.0 Yinzy · Nov 2025

Solid seafood in a clean, modern setting. I had a great time here. The oysters are incredibly fresh and clean, which is a big plus. Their paella is also a standout — rich, flavorful, and highly recommended. The monkfish, however, is just okay; pretty average and nothing particularly memorable. I’m not sure if they still offer the seabass tartare, but it used to be quite good. As for the desserts, they look impressive, but the taste is just average. By the way, we mentioned that we wanted to share everything, and they actually split almost every dish into two portions for us — which is much sweet. Big big plus.

★★★★☆ 4.0 Eric D · Nov 2025

I have travelled the world extensively over 40 years. I ate at all restaurants ranging from pop & mom’s to Michelin three stars. This is my honest review of the restaurant Ostra in Boston MA, USA. A seafood-focused restaurant where we celebrated my birthday dinner. We started with the lobster pasta, served with a nicely seasoned sauce. The pasta itself was good, though we would have appreciated a slightly more generous portion of lobster compared to the pasta and mushrooms. The lobster pieces were of good quality, just not very abundant — understandable given market prices, but still leaving us wishing for a bit more seafood. Next, we had the monkfish with mushrooms, which was well cooked, though the seasoning was a touch too strong for my taste; a more delicate balance would have made t
