We moved 8 years ago so we could be 1 block away from this farmer's market. It's open year round and has a good mix of produce and prepared foods, serving a very diverse community and helping bridge boundaries between neighborhoods.
We do a lot of our shopping there every week (milk, eggs, vegetables, spices, pizza, muffins, etc.) and every week spend a lot of time just catching up with neighbors and friends there as well.
A friend just started a bike-powered smoothie stand (pedal your own and get $0.50 off) and there are so many other amazing things there. - http://www.32ndstreetmarket.org/
BTW, while the name of the market is Waverly or 32nd Street, it is located in Baltimore City, please adjust the information as such.
