My wife (a Main Line native) and I, San Franciscans, will be spending a week in Philadelphia and are eager to try some of the Italian places recommended by Chowhounds. Since so many restaurants are BYOB, can anyone recommend some places to buy wine? I know the stores are state-owned, but our previous experience of the area was limited to uninviting stores with an armed state trooper eyeing us as we browsed the wine. Any suggestions? Thanks in advance.
