If you want to celebrate the spring equinox, the astronomical beginning of the spring season here in the Northern Hemisphere, on March 20 at 5:24 p.m., here’s an idea. Head over to Cafe Routier, 1353 Boston Post Road, Westbrook. They’ve already rolled out their spring menu, and it’s packed with goodies. The gnocci alla carbonara is served with an egg, guanciale, and pecorino cheese. The baby spinach salad comes with shaved asparagus, Easter egg radishes, feta, and slivered almonds topped with an herb vinaigrette. There is also a duck duet, a hangar steak, and more.
