I go out once a year with a group of cheerful and curious friends for a February dinner where cost is no object, for a tasting menu if possible. So far we've gone to the late Susur and Avalon, Perigée (under the original chef), Canoe, North 44 and Oro. Our faves so far have been Susur and Perigée. This year we're thinking about Nota Bene, Pangaea and a few other possibilities. Does anyone have a passionate endorsement for someplace we should go that will offer us an unforgettably pleasant and interesting experience?
