One of the highlights of Lollapalooza, we know you’ll agree if you’re reading this site, is Chow Town, the selection of food vendors running the gamut of high to low, many of them selected by Lolla superfan and golden food rock god Graham Elliot. And with 100,000 fellow fans competing for an Edzo’s Burger at noon, it’d be great to have a guide to exactly where the food you want is, right? As in, not just "It’s in Chow Town North" but "It’s right next to Lou Malnati’s." Well, that’s what Grub Street is happy to present. For the first time anywhere, we’ve got the stand-by-stand layout for both Chow Towns (subject to last minute changes and all that, of course), listing all 34 restaurants along Columbus Ave. in order, and all you have to do is download the jpeg here, put it on your iPhone, email it to your friends, tweet it to your peeps, whatever helps you and your friends get the chow that matters to you.
