My parents will be traveling to D.C. next week from Colorado and need some fun restaurant recommendations. They aren't into eating at super-expensive, high-end restaurants, would be more interested in restaurants in historic buildings and great views. Any suggestions would be appreciated. Also, what about Chinatown? Does it still exist and are there any fun places that they could try? They will not have a car, but access to Metro and good old fashioned walking. Would also enjoy recs for great bars to go enjoy a drink. Thanks!
