Chain Restaurants Change Philadelphia'sCharacter

"At the edge of every American city you will find the familiar shoulder of generic chainification - the Wendy's and Home Depots, the Old Country Buffets and Wal-Marts, and so on and on...And it is why the centers of great, old cities have remained so inordinately precious and such destinations. They're still chock-full of the oddball, the independent, the genuine, the family-run, the defiantly traditional, the funky and the organic - the very sorts of touchstones and eateries that have been erased so determinedly from the margins."
