With the Democratic National Convention to be held here in July, and its expected influx of 50,000 people, Philadelphia is more than ready to show itself off to the world. Thanks to a compact city center and plenty of bike lanes — plus a popular bike–share program — Philadelphia rewards exploration on two feet or two wheels. A college town, the city has a young vibe and a profusion of happy hours, as well as one of the most dynamic culinary landscapes in the country. The restaurant scene is expanding rapidly, from Frankford Avenue in the north to Passyunk Avenue in the south, discarding traditional “red sauce” Italian restaurants and working–class bars in favor of indie B.Y.O.B.s and elegant cafes. With an ever-increasing number of stellar museums, the transformation of industrial spaces into artist studios and a newly invigorated clutch of outdoorsy offerings, the city has never been more inviting — and not just to the Democrats.
