I worked in the Board of Trade building for decades. We would day-drink at Ceres once each year - it was the Monday after the December Friday expiration of Treasury options.
Any more often than that means you have a problem.
Underrated Chicago experiences:
1. Walk thru Jewel-Osco or Mariano's w a friend who knows all the corporate lore.
2. A morning drink at Ceres Cafe.
3. ISAC/Oriental Institute museum in Hyde Park.
4. Downtown-Chinatown water taxi.
5. Wrigley Park guided tour.

"There are more instances of the abridgment of the freedom of the people by gradual and silent encroachments of those in power than by violent and sudden usurpations."
