One thing I love about Baltimore is the farmers markets.
There are two within walking distance of where I live, one under the JFX that has tons of produce, lots of ready-made/to-order food, and a bunch of hand-crafted stuff. For our last anniversary, my girlfriend bought me a hand-made olive oil drizzler and artisan olive oil from there. I’ve gotten some of the best bread of my life there as well as the best lemonade I’ve ever had (from Adel at the Neopol stand).
I used to live one block away from the Saturday 32nd Street Farmers Market, notable because it stays open year round. There’s another market up at Loyola (I think on Wednesdays) and apparently this one on Thursdays. There are others in the county as well. With that and all the CSAs around, it’s very easy to get fresh locally-grown produce, meats, and other products at a very affordable price.
Also there’s the Arabbers, but I have yet to buy anything from them.
