If food carts are set up on private property – as was done at Oak Park's Pilgrim Church or Chicago's Goose Island for their food truck rallies – it'd be easier to deliver a high-quality product at a good price without encountering the problems that seem endemic to food truck rallies.
It's possible to have a wonderful experience at a purportedly lousy restaurant and a dismal meal at a much beloved restaurant. This principle I take for granted and, lately, have had demonstrated for me at the Grand Central Oyster Bar.
Oak Park is somewhat smaller than Brooklyn (which, if it were a city unto itself, would be like the second largest city in the U.S.) and Lyon (the second largest city in France), so maybe economies of scale don't apply. Still, how cool would it be for the Village to set up a rack of bicycles for residents and tourists to use as needed, secured with a credit card, of course, and perhaps funded by a local bank (looking at you Chase).
Ruby Streaks Baby Mustard greens require no cooking: I just rinsed and put into a salad. In a salad, the texture of the tiny shoots are prickly, kind of like frisee, a good contrast to mesclun, romaine or other larger leaves.
