I love Fairmount Park and the art museaum myself. Much of the city is either a ghetto (West Philly and the near north) or stuck in a time warp (South Philly and the NE). Cheap housing and good food, however, but I can get that in my dad's old nabe in Newark while still being in commuting distance of NYC.
I love center city Philly. But you go a few blocks north and it's a total dump. The houses are literally falling down before your eyes.
But Center City has really been cleaned up and revitalized.
New Convention Center, new Baseball and Football Stadiums in South Philly, Market Street Mall is HUGE and really nice, Liberty Towers and their street level malls absolutely sparkle, they are beautiful, downtown is clean, and Philly is known for having many of the best restaurants in the country.
I like Philly for the combo of big city atmosphere and small town down home warm friendly people.
I find New York a cold and strange place with rude people by comparison.
