Just stayed at the Peninsula for a work week and I have to say that I am both very impressed and surprised. Suprised because I can't really fault anything. The location is fabulous, the hotel building itself i immaculate, the service is sensationally good, the rooms are very large and in excellent shape, the restaurants serve fabulous food (try the Chinese Shanghai Terrace..very tasty), the gym and spa is world class at the 20th floor overlooking chicago. I could write a very lengthy review describing especially how good the service is but there is no need. Its a fantastic place, so if you are looking for a top notch classic place in Chicago and if you can afford it then it comes with my top recommendations. Its rare for a hotel to come across the way they market themselves, this one do, actually its nearly better than the marketing, which says a lot.
