It might not be all local food, but it is very affordable. They have heirloom tomatoes, actual real honest to god apples that look like real apples from the NC mountains, fresh corn, local grapes and inexpensive grocery items like celery, lemons, carrots, etc. They also have a garden center with seasonal plants which is a great place to buy herbs. You can also usually find some local baker or farmer with fresh breads, farm fresh eggs and organic meat.
Come Halloween, it turns into a sea of pumpkins. It's a great place to find a funky pumpkin (they like fruit and veggies that look real, not plastic here!). You really cannot beat the prices. I wish it was open more days than Tuesday and Sunday. There is also a seafood guy, but since i'm allergic I steer clear.
Remember to bring cash or a local check! Parking also can be dicey, there is a lot across the small side street for market goers.
