A long-standing Mainline favorite since its opening in 2000, Tango Bistro has recently renovated its building to be incredibly Eco-friendly. The roof has 88 solar panels that sustain the restaurant’s own energy. According to Cheryl Allison’s piece in the Main Line Times (“Conundrum: Encouraging preservation, conservation in township” April 2010), Tango was projected to save about 20 percent on its energy bill after solar panel installation. Tango has always recycled, but prior to the solar panel installation it was looking to reduce its carbon footprint even more. Despite the initial concerns outlined in Allison’s article, the construction plan proceeded in Lower Merion Township. Painted completely black, the solar panels are a remarkable addition to a Bryn Mawr favorite.
