what's the best thing to do with four days in Chicago?

<p>Millennium Park, Navy Pier, the Hancock Building, the Magnificent Mile (for shopping), Lincoln Park Zoo, all the museums, Cubs & Sox, Michael Jordan statue at the United Center, the neighborhoods (among others, river north, near north, lincoln park, wrigglyville, devon, andersonville, bridgeport, pilson, ukrainian village, UIC neighborhood, greektown, chinatown, little italy [what’s left of it] & get an italian beef sandwich at Big Al’s on Taylor St.), and at 4 AM visit Lawrence Fisheries at Cermack & Canal for the best fried shrimp you have ever had (open 24/7), and eat stuffed pizza at Giordano’s.</p>
