    Charming and thoughtful decor, down to “ ambiance” in the rest- rooms. Attentive wait-staff. Lobster tools nicely proportioned, and very tasty. Guacamole with crab meat is pricey, but a treat. Excellent for group experience and child friendly.

    First time at new location on 81st/3rd - beautiful corner spot with charming, elevated decor. Same great menu, great service. Best place for mussels in NYC! (Just please can you bring back the fun tshirts?)

    the noise level was quiet for us because we did not sit in the maindinning room. We sat in thje outdoor enclosed heated patio and it was very cozy and quiet. Otherwisw I would say it was very noisy in the main dinning room. All good with the food , service and just a lovely experience once again , as we do eat here a few times a year.

    Mussels were great. However, an up charge for Belvedere from Grey Goose and blue cheese stuffed olives, unexpected. Should have been told by the sever. I have no problem with a $30 martini if served table side in a nice chilled martini glass. Not the case.
