A quick search of the Fairborne's Fabulous Food Finder database yields two vendors flying the organic flag. One selling organic coffee and the other a BBQ vendor.
Located on the SW corner of Judson Ave. & Liggett St.
A four dollar bratwurst of a political statement about your food values, in the sodom and gomorrah of food for "the heck of it".
This comes off as being a bit hippy freakish preachy, but higher food values are tied to a growth industry - the organic and natural foods movement. It strikes me as a bit tragic that there isn't an organic foods pavillion to highlight Minnesota Grown and produced organic products. I've been absent from the Fair for many years and I hope to find more evidence. Please comment if you're aware of any other vendors/producers/growers or any guide for the same.
All this said, it's a fascinating world of organic junk food that we now live in. Food inputs that represent higher values which are assembled in ways that have little or no regard for the bottom line health effect are abundant. So you won't be clogging your arteries with hydrogenated oil, but the devil may care about calorie counts or nutritional value? Even so, I would personally feel a lot better about the Tom Thumb donuts if they were made with Minnesota produced flour, fried in organic oil, and dredged in organic sugar. How about a bottomless glass of chilly organic milk? I'll pay the premium.
