Pleasanton Farmers' Market

I've been going to this market since I moved to the area six years ago. It's great because it's year-round, and it's especially nice at Christmas to be able to buy the ingredients for meals and lovely gift items like jams, cakes, and olive oils. It's also right in downtown Pleasanton, near great restaurants and coffee shops. In the summer it can get hot, so go early (opens at 9:00).
