You have to go to Portillo's and get a BEEF. Order it just like this (u better write this down) Beef with, XXX Dip, side hot, chili minus.
Spend some time at the river walk in Naperville. And when night comes around, get a ride to Heavenly Bodies in Schaumburg. Tell them "Grover" sent you //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
There is way too much to do down there. You will be about an hour from downtown (depending on rush hour) so plan a trip to the city for an entire day. Hit rush street on Saturday night for sure. And after drinking all night head to Burritoville off of Archer and I55.
