There is practically no indication that behind an elegant patisserie and gelato counter on Main Street lies a small Art Deco restaurant with the atmosphere of a private supper club. It is lushly carpeted, gently lit, expensive, and the food is out of the ordinary. A few of its highly touted dishes are beef carpaccio, king crab leg and crabmeat salad, ricotta ravioli with Genovese pesto sauce, and veal chop Milanese with arugula and tomatoes. All the pastas are made from scratch. The coffee bar opens at 10 a.m. and, of course, the pastries star. A few outdoor tables are available in good weather.
