Cafe Nora, a casual Southern European restaurant along East 86th Street in front of Target, has closed after a more than 7-year run. Owner Jim Nethercott said he had to shut down Saturday because of falling traffic and other financial troubles. His sales were down 34 percent from two years ago. The landlord, Target, is giving Nethercott time to find a buyer, he said. Nethercott also had to shut down Ruth’s Keystone Cafe, across the street from the Fashion Mall at Keystone, about two weeks ago.
