I have been going to the Davis Farmer's Market for years. It has won many regional farmer's market awards. It is a very reliable market, held rain or shine. There is a great selection of locally grown produce, nuts, rice, and more, as well as all sorts of great locally made goodies such as apple juice, hummus, breads, dried fruits/jams, and more. Samples abound, and if that isn't enough food, there are good stands that offer lots of great vegan options, like my favorite vegan tamales (there are also veggie dogs, Indian food, and much more). If you go Wednesday night, the mood is more of a family night out, with more food stands and entertainment and fewer farmers. Saturday morning is the best time to go to get your groceries if that is what you're looking for (although I'd still go Wednesday if I happened to be around).
