    Classic proposals and good ingredients. Nothing outstanding and not worth a second trip. Service was excellent, although the busser was a bit overzealous at times.

    Food and service are exceptional. Very attentive and considerate service team. The dishes were all expertly prepared. The space however is much too loud and feels overcrowded with servers falling over each other.

    Creative menu. Top-notch service. Love dining at Ostra before walking over to The Wang for a show. The Ricotta Gnocchitti is amazing!

    for the price, while the taste was good the portions were really absurdly small. yes, i understand these are meant to be eaten as a 1st and second but that is impractical for a solo diner. i spent $120 and had to go buy more food after my meal.
