    I took my husband to Ostra for his birthday, and it was fantastic! The food was delicious, the staff very attentive, and the atmosphere relaxed. We parked in the garage across the street which was very convenient. The crispy native oysters were the best we’ve ever had. I really enjoyed the grilled sea bream, and my husband loved the paella “Valenciana style”. Our knowledge waiter recommended wine that paired perfectly with our meals.

    The food was excellent, however the service was not. We had dinner there, and throughout the meal the service was extremely slow. After dinner, we went to the bar and had a drink. When we went to order a second drink, we were informed that last call had already happened, however no one informed us that it was last call. When we asked the bartender, he said that he was supposed to inform us but did not. Overall very disappointing end to an excellent meal.

    Bar staff was amazing. The teamwork was flawless and they were just incredibly pleasant people. Food was immaculate as always. A perfectly cooked Fillet and the delicious lobster made the night. In and out quick as we had a theatre show.

    The meals at Ostra are always excellent. We would normally give five stars for the whole experience, but a Calamari failure this time brought down the score. Don’t let this dissuade you: the calamari was an anomaly.
