8:30 — Start in Millennium Park before the crowds. Cloud Gate — universally known as the Bean — reflects the skyline best in low morning light, and you will actually have room to photograph it.
10:00 — Cross to the Art Institute of Chicago, one of the world's great museums. Prioritize the Impressionists, Nighthawks by Edward Hopper, and American Gothic by Grant Wood. Two hours minimum.
12:30 — Deep-dish lunch. Lou Malnati's and Giordano's are the famous standard-bearers; order when you sit down, because a true deep-dish takes around 30–45 minutes. Split a small — it is heavier than it looks.
14:30 — Walk the Chicago Riverwalk, then board a river architecture cruise — the single best thing to do in Chicago. The Chicago Architecture Center's boats are the classic choice; ninety minutes among the towers explains the whole city.
17:30 — Golden hour above the city: the Willis Tower Skydeck and its glass Ledge boxes, or 360 Chicago up north for a skyline-with-lake angle. Book the sunset window in advance.
20:00 — Dinner in the West Loop, the city's restaurant row along Randolph Street's famed corridor. Reserve ahead for the big names, or walk in for tacos and wine bars.
22:00 — Chicago blues, live. Kingston Mines in Lincoln Park runs two stages late into the night; Buddy Guy's Legends downtown is the other pilgrimage site.
