Mary Ellen Carroll's Open Outcry -- a commission for Feast -- is the latest iteration of a long-running project in which she creates site-specific conversations around meals under the title Itinerant Gastronomy.

Open Outcry is a commodities-inspired five course lunch presented next week at the financial gallery at CME Group in the Chicago Board of Trade. The carefully selected guests -- including an economist, a trader, a sociologist, and others -- will eat and converse in a sculptural table designed by architect Simon Dance in a viewing room high above the active trading floor. The meal, the setting, and the seating are all intended to "catalyze useful conversation about the intersections of food, power, finance, policy, and art."

A video documenting the lunch and the tables themselves will be displayed at the Smart as part of Feast, beginning February 16.
