Using Google's public transit option is the best because you'll need to use some combination of Metra and CTA bus and walking, to and from Harris. You can set Google for arrival times (like arrive at Harris 15 minutes before the show). Just note that on Sundays the last train usually leaves the Loop around midnight. Make sure you don't get stranded!
Easy check the metra from northbrook and connect to the 60 bus right outside the station. Takes you directly to the harris
Use Google and set it to public transportation. It will show you all the CTA buses and El options.
