My friend Katie Loeb runs the bar program at Oyster House (1516 Sansom Street), so I'm not completely unbiased, but I very much enjoy both raw and cooked options there. One of their specialties is fried oysters with chicken salad, a Philly tradition dating from a time when oysters were cheap and chicken was expensive. Or something like that. Food's good, drinks are good, there's pretty much always a cask beer on. And Nodding Head brewpub upstairs makes exceptional, moderate alcohol beers for pre- or post-imbibification.
