When people fly from Baltimore, they stock up on refrigerated crab meat; hardly an ideal carry-on for a cross-country flight. Chicago's token to-go food, on the other hand, is far more tantalizing. Eli's Cheesecake—sold whole or by the slice—puts the New York stuff to shame. Whether you're into chocolate chip, candy bar, strawberry or creamy original, you'll find all your favorites on sale and packaged to go at this little kiosk from heaven. Cheesecake heaven.
