Great Hotel and Service - with Two Exceptions
The Ritz-Carlton Hotel in Chicago is an elegant hotel in a great location with the usual outstanding service by almost every employee. 
One drawback causing me to give a less than a perfect rating was that there was no radio in the room, and they did not even have one to bring to our room! I have never stayed in any U.S. hotel previously that did not have an FM radio in each room.
Also, the restaurant had less than enthusiastic service to put it kindly (reviewed elsewhere).
