Considering the area in which this is held it is not bad as far as farmer's markets go. I suspect this could be why there are so many 5 star reviews. I can say that when I suggest a trip to the farmer's market, this is the only one I think of. I once went to another one in Champaign. It was three pick-up trucks in a parking lot.
This is slightly better. There are more vendors, but I wouldn't call it "large". There are enough vendors selling vegetables that it is in your benefit to walk around first and compare prices and freshness. Although, if you can suggest that people walk around the whole market before purchasing vegetables that pretty much makes it hard to argue that the market is "large".
Initially my husband and I went to this market just to get fresh vegetables that we could not grow ourselves (green beans, peaches). Over time we have branched out and tried some of the other products such as the cheeses and baked products. We have always been pleased with our purchases.
If you go here with the intention to buy all your groceries for the week, you will probably be hungry by Tuesday. However, if you go here intending to supplement your weekly shopping trip, you will probably be happy.
