Great market. The anchor of the whole market is the McClendon's organic veggie stand. This is by far the best produce in the valley. The prices are fair and the selection is huge. Get there early to view the whole selection. The avocados are very good. Loose lettuce allows you to pick your quantity, which is nice for smaller households. Squash selection is great and the honey is amazing.
Other notable features of the market are the cheese curd stand, QC Olive Mill has a stand, and there are a number of great bread vendors.
Finally - Try the toffee. It is amazing.
Very nice market that is laid out to handle the foot traffic, so it does not feel too crowded. Parking is typical for Old Scottsdale.
