Make a reservation for dinner in Newton at Andre’s Restaurant, where the menu changes every two weeks to reflect what's in season. Past the copper bar lie two brick-walled dining rooms where you can have a five-course meal ($50 to $60) or order dishes like veal paillard over goat-cheese orzo ($36) and pan-roasted chicken with sweet corn and foie gras pudding ($25) à la carte.
Head to Berta’s Chateau in Wanaque for old-school Italian-American cuisine served in portions that won't leave you hungry. Open since 1927, the restaurant caters to loyal locals who have been coming here for decades to enjoy plates of handmade pastas—try the tajarin with porcini mushrooms ($23)—and veal sweetbreads with Madeira ($29).
Treat yourself to a three-course meal ($75) at Restaurant Latour, part of the sprawling Crystal Springs resort and likely the most formal dining option in the Highlands. Cape May oysters, Hudson Valley foie gras, and other local items fill the seasonal menu, while the award-winning wine cellar boasts more than 9,000 labels and more than 100,000 bottles.
