When in Chicago you must go to Nine! There is one in Vegas but I have never been to that one. I have been to the 9 in Chicago twice. The lunch and dinner are superb, as is the service! If you are there for lunch try the Ceviche...I've eaten a lot of Ceviche in my time and that is by far one of the best ones. The Steak is great and the desserts are fabulous! Not to miss.
