If you’re in the neighborhood and love bargains, check out Warehouse No.4, a hidden gem just a few miles west of downtown Highland Park. As the name implies, it’s a bare-bones warehouse, one of four on a frontage road along Route 41, but as Gena Rogers (co-owner with Jackie Chilow) points out, "antique lovers will go anywhere for a great find."We saw lots of vintage chandeliers ($200-$1,500), an antique French armchair ($400), and a four-piece Lucite dining set ($2,400). 1596 Old Skokie Rd., Highland Park, 847-831-2660.
