The DC pop-culture site Brightest Young Things has been making funny flowcharts on what you can do in various neighborhoods: last year they did one on Columbia Heights (do you want to dance? Are there vegans? Do you want tequila?) and now they've done one on Petworth, which also includes places in Park View and Columbia Heights. Pretty fun.
Sadly it includes the now-closed Crane & Turtle and soon-to-close Domku, but otherwise is pretty neat. Click the image for a bigger version or visit their site.
