Helen’s, the intimate North Bethesda restaurant at 11120 Rockville Pike, is celebrating its first birthday with a new prix fixe menu featuring duck a l’orange, halibut with sherry sauce, Maryland lump crab cakes and other specialties of veteran chef Helen Wasserman. The longtime D.C. caterer spent two years renovating the century-old building, which previously was home to Addie’s. She also handles bar mitzvahs, weddings, corporate parties and other private events. Call (202) 483-4444 or visit www.helensnorthbethesda.com.
