    Hamachi was amazing! Grilled octopus was very good, although I have had some great octopus so it was hard to give it an amazing score. Great bartender! Easy in and out. Would visit again next time I am in town.

    Lovely meal at the bar. We were well taken care and had plenty of space. It is a nice set up for a quick meal but we were never rushed. Food was awesome too.

    A colleague chose this location for a business dinner. If you are on any kind of budget limitation, I would stay clear of Ostra. However, with the help of an amazing hostess and server (Lara), we were able to choice some amazing options that fit our budget. The oysters we the best I've ever had! Wine- amazing! Fish- can't go wrong. The presentation of the food was personal and intimate making each guest feel special. As the evening progressed the room got louder and became difficult to have a conversation where everyone at the round table could hear properly. The lighting grew dimmer as well which made it difficult to share printed material. In the future, go early for less noise and more light. I will definitely be back for a special experience with my loved ones! Thank you, Lara for your incredible support through out our experience!

    South Bay oysters, yellowfin tartare, sea bream in Trevisano leaf, chocolate torte: It was sublime, beginning to end… a meal I’ve kept going back to in my mind since I had it a few days ago. Thank you.
