Love Chicago! Fly in 2-3 times a year for the weekend. +1 to Iwan Ries, it's an institution! Giordano's is a classic Chicago pizza joint - there are a number of locations scattered throughout Chicago. Although not quite the decadent capitalist field trip that it used to be, walking both sides of the Magnificent Mile, North to the Gold Coast, and South into the business loop, theater district is a great way to spend a day. It's hard to have a bad meal in Chicago, and there are some stellar dining opportunities at all $$ levels. Another hint if you are staying downtown - take taxis everywhere. You'll spend nearly as much trying to park at most places, and will save alot of time. Have fun!
