Head to Pentagon Row for Main Street charm and big-city selection. This outdoor, walkable shopping center features dozens of specialty shops. Get your glam on at Denim Bar (with personal fittings from denim guru and owner Mauro Farinelli) plus Ann Taylor Loft, DSW Shoe Warehouse and Sur La Table. Two spas include eponymous Elizabeth Arden Red Door and Jouvence Aveda. Dine at Lebanese Taverna or Thaiphoon, and finish it off with a pint at Siné Irish Pub. Stop by the Arlington Visitors Center, also located here.
