The market has always been a favorite of mine. It can get a little crowded but if you go early on a Saturday, I think it can be worthwhile. This is the best place to buy your fruits and veggies and I have noticed that a lot of people buy their meats from there too but I have not as of yet.
If you have guests coming into town, this is a pretty cool tourist attraction, as it is one of the largest markets in the Midwest. Grab some fruits to make smoothies and cocktails
My favorite thing to eat when I'm there are the polish dogs with sauerkraut. Must try!
