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 even on a packed Valentine’s Day night, which says a lot.
Overall Ostra just does date night right. Great energy, great food, and a place that actually feels worth going back to for special occasions. We’ll definitely be keeping the tradition going next year.
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 was truly impressive. This is what real leadership looks like — present, humble, and service-driven.
Management should pay close attention — he’s a keeper and deserves recognition (and a raise).
We will definitely be back.
$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. Very attentive and prompt.
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.
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 the dish shine even more.
For dessert, the restaurant surprised me with a birthday inscription and a small candle — a very thoughtful gesture. Interestingly, the dessert turned out to be the highlight of the evening: simple, well-executed, and delicious.
The service was friendly and efficient, and the setting is charming, with high ceilings and well-spaced tables that provide a pleasant sense of privacy.
Overall, a nice seafood restaurant with attentive service and an attractive dining room.
However, one thing to note is the wait time. We had to wait approximately 40 to 50 minutes before the food is served, which was longer than expected for a place of this caliber. While the ambiance and service helped make the wait more tolerable, it’s something to keep in mind if you’re planning to visit during peak hours.
That said, once food is served, the experience truly shines. If you’re a food lover with a bit of patience, this restaurant is definitely worth the visit.
We started with oysters 5/5 and razor clams 5/5. Both were incredibly fresh, clean, and thoughtfully prepared. The ricotta gnocchetti followed and was an easy 5/5. Rich, balanced, and comforting without feeling heavy.
For mains, the monkfish 5/5 and sea bream 5/5 were outstanding. Both were cooked perfectly and showcased how precise and confident the kitchen is.
Dessert sealed it. The panna cotta 5/5 was light and elegant, and the warm chocolate tart 5/5 was exactly what you want to end a great meal. A crisp glass of Chablis 5/5 tied everything together perfectly.
The service matched the food. I do not remember our server’s name, but he was excellent. Attentive, calm, and genuinely cared about the experience. Even on a busy night, the entire team worked seamlessly together. The GM, Trevor, stopped by and was truly hospitable. Nothing felt forced.
We were there to celebrate walking into 2026, and Ostra helped make it memorable. It is hard to build a great team, and even harder to sustain one, and Ostra has clearly figured it out. I cannot believe it took me this long to come here. I will absolutely be back.
