Probably my favorite museum in DC, and the courtyard is easily one of my favorite places in the city. I always really enjoy the exhibits they have on offer and they seem to rotate them at a pretty good rate. There's always something really interesting to explore there. The Diane Arbus exhibit that is there right now is pretty small, but man did it make an impression.
If you're in the city and you haven't gone to have lunch in the courtyard yet, you're really missing out on something.
