Polish your shoes and dress your smartest, 'cause you're going to want to look the part as you cruise down world-renowned Magnificent Mile.  Designed to rival New York's 5th Avenue and Paris's Champs Elysees, the Mile is big on history and haute couture. From the Drake to the Allerton, you'll check into some of Chicago's swankiest hotels like so many celebs and statesmen before you. Then saunter down Chicago's best street of shopping and marvel at some of its most magnificent architecture.  Grab a slice of deep-dish pizza at the restaurant where it was invented, then wash it down with a drink at the famous Billy Goat Tavern. When you finally reach the banks of the Chicago River, you may feel as maxed out as a tourist's credit card.
