We doubt there's a more beautiful workspace than the former trading floor at the Minneapolis Grain Exchange. With its floor-to-ceiling windows, ornate woodwork and columns, and paintings depicting the Mill City's industrial past, the newly renovated 110-year-old space is now home to business incubator CoCo, short for Coworking & Collaborative Space. The floor where commodities traders once hollered bids for wheat, corn and oats is now leased to individuals, small firms and entrepreneurial groups. Workstations can be rented for as little as $50 a month whereas corporate "campsites" go for $2,750 a month. As Google CEO Eric Schmidt remarked when he visited, "People want to work in a group. People are social." And if you want to be social in St. Paul, CoCo has space in a former warehouse in the Lowertown neighborhood.
