Kudos Phoenix! I have been starving for some culture in Phoenix for years! The Downtown Phoenix Market is a breath of fresh air in a previously stagnant city. The raspberry cocoa preserves and spicy o's (think jalapeno relish) I purchased from Terra Verde farms were unique and delicious! I also found the Arizona Bread Company's products and Dr. Hummus' treats to be irresistible, among others. There are tons of great vendors. Everyone is friendly, and the samples are delectable.
While it's a little small for a major city's farmer's market, it has great potential and I highly recommend it! I gave it 4 stars because I'd like to park there for free (currently costs $5) and the summer months are going to be awfully toasty (but they do have misters).
