JFM, please, please, please try to do something like the DeKalb County Market in Atlanta. That would be a major attraction for anyone close to Jacksonville. See what that place is like at dekalbfarmersmarket.com. I've long thought an operation like that would be well suited for the Southside Generating Station parcel which should be big enough to hold the store(s), parking, and space along the river for outside activities. The DeKalb County facility is a place you can spend hours in just looking at foods from around the world available nowhere else.
I've noticed that JFM sells all sorts of citrus, but amazingly has no juice bar. Many other possibilities are also lacking and an expansion would open a helluval lot of new possibilities. Notwithstanding a prior post, I think getting a little more upscale would be a wonderful idea. The whole place doesn't need to become more expensive, but some residents might welcome a place to get really great meats, seafood, flowers, and so on, in one venue.
GO FOR IT. If you build it I will come.
