Help a farmer's market newb

Today I visited the Green City Market for the first time ... it was also the first time I've ever been to a farmer's market since I developed an interest in cooking. Picked up some sweet corn, fennel, basil, a Red Hen baguette, and some flowers.

I was just wondering if any vets of the market here have pointers on specific producers or items to get at Green City? Like someone with killer tomatoes, etc.

Thanks!
