Anyone who happens to be downtown–specifically, on Michigan Avenue–this Monday from 10 AM to 3 PM should be forewarned: “lunch police” will hand out “tickets” to people waiting in line for restaurants, while rickshaws will round up hungry-looking pedestrians and deliver them to Pioneer Plaza (just north of the river, south of the Tribune Tower and across the street from the Wrigley Building) to try DiGiorno’s new Flatbread Melts, a microwaveable pizza sandwich consisting of various combinations of cheese, vegetables, and meats inside a folded flatbread. Or visit this website on May 18th to print out a coupon for one free melt in a store (limited to the first 100,000 visitors).
