Arlington's largest live music venue attracts an energetic crowd. Its Art Deco-era style, large dance floor, lush lounge areas, and 60-foot bar would be enough for a memorable night out on their own, but the real draw of the Clarendon is the enormous rooftop. At more than 2,000 square feet, and with seating and its own bar, the rooftop is bigger than the interiors of many nearby nightspots. Check the schedule before you go as you may hear live rock and roll or a D.J. spinning anything from '80s to 'Top-40' hits.
