there are plenty of really good restaurants in this town that you can get in to with little or no trouble (or just by going old school and making a reservation a couple of months out).
Another, related point is that the newest, hottest places are only a small slice of our restaurant scene. There are many excellent restaurants in all categories which have been around for several years (some for many years). And if YOU have never been to a restaurant, it's still new TO YOU. There may be a handful of people here who have been to so many Chicago restaurants that there aren't any they still want to try, but if so they are very, very few of us. I bet most of us are like me. I keep a list (an actual list, although there are probably others who do so mentally) of restaurants I've never been to and want to try. That list never gets shorter, because the number of new places I hear about adds places to the list faster than I can take places off by trying them. And of course the other dilemma is choosing between new places vs places I've tried and enjoyed.
When you think about it, though, all this means is that there are always many, many places in Chicago to choose from. In that respect, we are fortunate to live in one of the greatest food cities anywhere.
