You can’t come to Chicago without having some deep dish pizza. Check out Giordano’s. It’s the best pizza, it’s family friendy and there are a lot of locations downtown.

Taxis can be from 10$ for a 5 minute ride. Also check out mellenium park and wrigley field

Depends on what time of year - Shedd a good place for kids any time of year. For a 3-year old, perhaps the Children’s Museum at Navy Pier would be a better choice than Natural History. If it’s nice outside, Lincoln Park Zoo and Petting Zoo are free (and GREAT) and the 151 bus goes straight there from downtown.

Re: restaurants, Rainforest is a chain, there are more “Chicago” places to choose from, I agree deep dish pizza is more unique and still kid-friendly, like Giordano’s. Taxi cost depends on where you are going - busses are easy and I think $2/person. Parking is expensive, don’t drive in if you can help it - if you are flying, take a cab or train in, don’t bother renting a car, you won’t use it and it’s like $30/day to park downtown.

navy pier or go see the cubs play at wrigley. its just alot easier to take a bus to the muesums. go see the fountain and theirs alot of really good resturants go to lou malnatis and get the deep dish pizza. or bob chins crab house is good. gino’s east.
