As far as direct purchase goes - there's a vendor with free-range bison and beef at the Crystal City Farmer's Market on Tuesdays.
A dining option in VA is Restaurant Eve in Alexandria, supplied by Polyface Farms (of Food Inc notoriety) in the Shenandoah.
Spoke to the new owners during the final months of Three Pigs (they were NOT happy to accept my coupon book discount) and that's pretty much it - they couldn't wait to start the renovation.
The owners are greek - possible influence on the menu?
The location, to be sure, is cursed.
A couple years ago it was "Charley Horse Cafe", which was also pretty good.
The new Asian Kitchen restaurant is actually not bad at all. I had a teriyaki and sushi lunch there last week and was impressed with the sushi quality.
The main problem NOW is that you've got a chinese/sushi restaurant down the street from established chinese and sushi restaurants in Lee Harrison Center...the writing's on the wall.
