We will be in Washington next week and will be spending 2 days visiting the Smithsonian Musuems and art galleries. Will be based near Dupont Circle off Connecticut Ave). Don't have plans yet for 3rd day, but probably in same general vicinity or National Zoo. Looking for hearty breakfast recs, quick (but good) lunch recs near the Mall, and dinner options near Dupont Circle or elsewhere. We won't have access to car, but public transit is supposed to be good. Have been recommended Old Ebbitt Grill near White House for seafood happy hour (?), Tabard Inn for jazz brunch, Paul's on Pennsylvania Ave. for breakfast. Are these any good? Any other suggestions? Thanks!
