The decision has been made: Italian in Philly Sat. night. Staying at an airport hotel, so not having to cruise around too much would be a bonus. The front runners are (in no particular order):
Osteria -- read some positive reviews
Il Portico -- menu looked good
Porcini -- been there, liked it, would go again
Le Virtu -- I saw the thread on this, mixed reviews.... but I *really* like the looks of their website / menu.
Your invaluable input is, as always, very much appreciated!
