There will be a group of 9 of us, 6 teenagers 3 adults, in the DC over a weekend. We will be eating a fair amount of hotel food but will be shaken free for some meals. Most of us have traveled together before and know that we would rather have something local and Road Food 'ish than something corporate and typical what-you-think-teenagers-would-want. We are staying in Arlington close to the airport but are fine taking transit.We will also have free time in Georgetown, the National Mall and Pentagon Row. Suggestions?
