    I had not dined at Ostra since right after they opened. The experience was as good as I remember. The food was outstanding, as was the service. Our waiter asked in advance if we had theater tickets and ensured we served in a timely manner, but didn’t feel rushed. I will definitely not wait as long yo dine there again!

    Our entire experience at Ostra was wonderful. We had a perfect corner table for two at the window as requested, a lovely birthday note, and fantastic service by Jose. Our meal was absolutely delicious: started with a pea pod salad, and our salmon and branzino entrées were perfect. We will definitely return.

    This was our first visit at Ostra. We celebrated our niece's birthday. Thank you for the lovely touch of placing a hand written birthday wish on the table. Our server Christopher and his colleagues were wonderfully attentive but also allowed us to pace through our dinner in a relaxed manner. We enjoyed the gnocci with lobster. The arugula salad (a special last night). We enjoyed the monkfish entree and also enjoyed the oven roasted branzino. We also ordered the shishito peppers and the delicious side of mushrooms. We ordered a chocolate torte in advance of the meal as a mini birthday cake. Thank you for a lovely evening.

    Certainly! Here's an edited version of your text for improved flow, clarity, and grammar: --- We were completely taken by surprise by this experience. It was the final meal of a long, busy weekend in Boston, and it turned out to be exactly what we needed. From the vast selection of delicious mocktails to the rich and flavorful decaf coffee, we were utterly smitten. The meal began with a bread course: a petite loaf of sourdough paired with a small dish of olive oil, topped with a dollop of butter. Simple perfection. My wife and I love to share courses, and while this can sometimes pose a challenge, it was seamless tonight. We started with the salmon tartare, elegantly presented with caviar and crème fraîche, served under a smoke-infused dome. Wow. The toasted brioche that accompanied it was probably the least memorable part of the evening, but it hardly mattered. Next, we enjoyed the Metze salad course, featuring a special arugula salad dressed in heavenly truffle oil and a crisp shaved snap pea salad with a delightful vinaigrette. For the main course, we shared the lobster. It was served in a light consommé, perfectly prepared and ready to eat, with two butter options for dipping (though it hardly needed them). On the side was a medley of roasted vegetables and puréed squash, a dish so satisfying it could have stood alone. For dessert, we chose sorbet: two scoops of coconut yuzu and one of apple cider. The latter tasted like apple pie, offering the perfect blend of flavors to conclude the meal. It was a perfect, leisurely dining experience. Thank you. --- Let me know if you'd like further adjustments!
