I just returned, and I have to say that while still small, for a first year effort, this market is impressive!
Vendors were quite varied. Busa and Hmong farms were both offering beautiful produce with very little overlap in content. Highrise bakery had a veritable mountain of amazing breads, Danish Pastry house had decadent sweets, and the Medford square book shop cafe (sorry, can't remember the name) was also selling a variety of baked goods. Mama Mia was serving prepared italian dishes, and I think they also had a stash of fresh pasta for cooking at home too. There is a stand that sells vietnamese coffee, and one that has home made condiments for sale.
If you are in the area, please stop in and support this fledgeling effort - it's on River Street, just about accross the street from chili garden.
