Are these in season? I have not seen fresh figs anywhere in Philly!
There is a farmer who frequents the Fitler Sq market who often has them (Highland Orchards of DE) but I believe figs usually come out mid to late summer.
Try the produce market in the marketplace area (downstairs) in the Comcast Center. Also, I've had good luck finding them at Iovines in the Reading Terminal Market, though not recently.
