We recently visited the Pavilion, our favorite place to eat lunch on the Mall. The P is located between the West National Gallery of Art building and the adjacent Smithsonian building. If you see a large fountain and a bunch of outside sculpture, you're there. What is available at the P are pre-made salads and sandwiches of pretty good quality, as well as soft drinks, water, beer and wine. You can sit in the air-conditioned building, or sit outside in the fresh air. The bathrooms are clean. this trip we had just walked several blocks, so we chose to sit in the A/C. I might note that the cost of a salad or sandwich plus drink is about $10, which may be a bit steep for families. That may account for generally quiet atmosphere - a bit different from the popular eating places in the Art Galleries and the Smithsonian buildings. This spot is a bit hidden, which for me is great amongst the bustle of the popular nearby tourist spots.
