David, my family spent a few days in Chicago a couple weeks ago and I was disappointed we didn't see any food vendors on the street. The only thing close was a vendor at the Bean. My wife grew up near NY and I was near Philly, we were both used to good street vendors. We wanted to give our kids the experience and were disapointed. I never did get one of those famous hot dogs - but I did eat Chicago style pizza three days in a row. What a great city - we wished we had more time and money. We'll come back next summer when the Cubs are in town.
