Is there parking on site? If so, what is the price for parking?

There's underground garage parking right there. Very convenient but it is pricey. You can find rates here. https://www.millenniumgarages.com/art-institute-chicago/

I second Donna

Here's a fun tip. On Saturday , Chicago's French Market has parking for 10.00 all day. Yes it is a twenty minute walk to The Art Institute. The reward is the lunch you can have at the French Market and the Crepes for Desert.

It was 25 dollars for us to park in the underground parking. But very convenient and worth it

Yes available no idea about the price
