I just want to say that I am truly sorry. Having been admonished by friends and co-workers alike, I pledge that when I visit Chicago to avoid Philly cheesesteaks and to sample the best that Chicago has to offer. Deep dish pizza, Ditka's, and roast beef will be just some of what I hope to taste and Philly cheesesteaks will be forbidden. Thank you to everyone who replied and I can't wait for what should be a spectaular visit. Thanks!
