Hi there - new member to egullet. I was led to this site after doing a search on Charlie Trotter reviews for an upcoming visit with my husband in October. We both just read "Lessons in Service", and, being that we work in the food industry, are intrigued to the point of making a pit stop in the Chicago to eat there on our way to Napa. I must admit that some of the posts on this thread have ignited concern, however dining at CT is as much about research and expansion of knowledge in restaurant operations (what to do, what not to do, e.g.) so I think we're going to forge ahead and keep our reservation. I was chatting with an acquaintance that is well-established in the Chicago area and says he dines at CT monthly. He mentioned that I should make sure that I tip the host/hostess and make sure that I'm "dressed appropriately" (beyond the required jacket???) because he has heard of incidents where people that showed up with advance reservations were never seated because the host/hostess weren't tipped and "didn't like the way they were dressed." Now, this seems completely ludicrous to me and I'm thinking that my friend was really just blowing smoke out of you-know-where...HOWEVER, has anyone ever heard of this scenario?
