Red Sky has anchored the fine-dining scene on “the quiet side” for nearly 20 years now, long enough to be called a classic. Meals take New England ingredients to creative heights, using French and other Continental techniques and accents. Begin with intriguing starters such as organic chicken liver pâté, baked oysters stuffed with crab and bacon, duck-pork sausage, or a crispy, layered polenta. Salads here are excellent; main courses could include a coriander-crusted piece of seared tuna, a chicken raised down the road and served with cranberry sauce, a round of grilled lamb bathed in Dijon mustard, citrusy scallops over Basmati rice, a pan-roasted breast of duck with a wine sauce, or maple-glazed baby back ribs. Finish with a house standard: toasted gingerbread with caramel sauce and brandied whipped cream, or else one of the sorbets or ice creams.
