Stop 1, Millennium Park. Stouffer's Top of the Rock restaurant, high atop the Prudential Building overlooking Michigan Avenue & Grant Park. In the late fifties & sixties, this was the big-deal place to take your date, your wife, or out-of-town guests--assuming, of course, that they weren't interested in the view, since they couldn't really see it through the head-high cafe curtains. Here's the real question, though: why are they eating dinner at 8:00AM? ChicagoBart606.
