The Ballston Farmer's Market (Fridays 11am-3pm) is in its 2nd year, and while it was exceptionally weak last year, it is good this year. They ahve cooking demos at 1:30, and the last 2 weeks was Willow's demonstration, although last week's was a bit weak. They don't have that much in the way of produce, but one of their bread vendors (baguette republic) is good, although they are also at Clarendon Market. There is a stand with argentione and mexican chorizo, and chimichurri. There is a guy who sells great coffee from his plantation in Honduras. There is a great goat cheese vendor who has soft and hard cheeses. Oh, and a guy with sauces, rubs, spices, chutneys, etc...
The Clarendon market (wednesdays 3pm-7pm) is also good, and has more veggies and fruit. The hard times chili dog stand is there mon-friday 11am-6pm...so you can get a chilidog while you are there.The
Courthouse market (sat 8am-noon) is great as always. I usally combine it with a trip to Earl's Sandwich Shop. He makes several of his own coldcuts.
