All-Purpose Pizza, web site, 79 Potomac Ave SE, Washington, DC, right by Nationals Stadium, there is also a branch in Shaw, 202-629-1894 (Metro Trip Planner – opens in new window) [Google | WaPo | Washingtonian | TripAdvisor | City Paper | Ylp]
One of the five best pizza places around, with some innovative pies for instance including honey, clams, or chili. The salads and appetizers are especially good, and they also serve New Jersey style Eggplant Parmigian, and described as such on the menu. Not off the charts good, but excellent and somewhere you can always look forward to dining at.
