My family has dubbed the Omni in Chicago "Fawlty Towers" because there always seems to be something wrong. This time our room was right above the kitchen and the odor of cooking grease wafted through our bedroom all night long. It smelled like a greasy spoon restaurant and it permeated all of our clothing. The bedroom window was bolted shut, so we couldn't get any fresh air into the room. With the amount that the Omni is charging for a room, they should have a much better ventilation system.
