We love eating fresh steamed seafood, Clam Chowders, etc, at this open air fish market located on Maine Avenue at the Waterfront in DC - No eat-in area though. Suggestion made by AmericanGuestHouse innkeeper.
American History Museum - Closed for renovations however you can still� see some of its treasuries at the special exhibition being shown at the� Air and Space Museum. This location is about 2 miles from the American Guest House - a non assuming b&b in Washington DC.
