When the weather turns in Chicago
The Loop Pedway links parts of downtown underground, though it is patchier and worse signposted than Toronto's or Montreal's equivalents. Better to commit to one large interior, since the Art Institute, the Field, and the Museum of Science and Industry each fill a day alone. The Chicago Cultural Center's Tiffany dome is free. Architecture cruises sail in rain but not lightning.
Chicago's museums, and which one to pick
The Art Institute runs $32 for out-of-state adults and $26 for seniors and students, free under 14, and holds American Gothic, Nighthawks, and A Sunday on La Grande Jatte in one building. Illinois residents pay $5 less with free Thursday evenings in summer. The Field Museum is free every Wednesday through 2026 for Illinois residents showing proof of address.
What to eat in Chicago
Deep dish is largely a visitor's order; the weeknight local pizza is tavern-style, thin and cut into squares. Italian beef arrives dipped, sweet or hot, from Al's or Johnnie's. A Chicago dog carries celery salt and sport peppers and never ketchup. Pilsen and Little Village cook the city's best Mexican food, and Devon Avenue runs South Asian by the block.
What first-timers get wrong in Chicago
CTA fares rose in 2026 to $2.50 on buses and $2.75 on rail, the one-day pass now costs $6, and the three-day pass was abolished outright. The Blue Line from O'Hare adds an airport surcharge on top. Wind off the lake makes the thermometer reading a lie in both directions. Tip 18 to 20%, with tax added to the menu price.
What things cost in Chicago
A day of CTA travel is $6 and a week is $25. The Art Institute at $32 is the steepest single ticket in the city, while the Field costs nothing on Wednesdays for Illinois residents. Lincoln Park Zoo, Cloud Gate, the Riverwalk, and the Cultural Center are all free. An Italian beef comes in under $10 and defeats most appetites.
