I will be at IAD tomorrow picking up family members - but there is an almost two-hour gap between when my parents' flight arrives and when my sister's flight arrives. I'd like to find someplace where we could sit and have a drink or a coffee or something while we wait for my sister, rather than just hanging around baggage claim. My general IAD strategy is getting in and out as quickly as possible so I am not sure of the answer to this - is there anywhere at the airport that is outside security and would fit the bill? Or, if we were to leave the airport, is there any place close by we could go, without driving all the way to Tysons or Reston?
