The Conrad Chicago is a Michelin rated hotel, so I was expecting great service and wonderful accommodations. Well, only one part of that was correct. The rooms are indeed nicely furnished, but the service was terrible! The concierge was unable to find my room reservation (I reserved online and even had the email confirmation) and wasn't very helpful in getting me a new room. I ordered room service, and the wait time was so long that the food came up cold. I mean, I understand that it would take time to get the food prepared and up to my room, but really? For the price I paid, it was definitely not worth it, and I would never use this hotel again.

this is my new favorite place to stay in downtown chicago, and I've been to this hotel at least 4 times. the rooms are clean, wonderfully designed and comfortable. The staff is friendly, service focused - and the restuarant is great, especially for the breakfast fruit crepes. Love this hotel. It's a great location, very good and consistent service and quality .

Rooms are so dark we had to insist they bring lamps so we could see. The room we had at almost $400 a night was dingy and small. Don't mistakingly think the Hard Rock Cafe is there, it isn't. They have a Chinese restaurant that is overpriced and limited on items. The room service menu is broken down in terms of times you can order certain foods. When my wife wanted a milk shake we had to call the Manager to have it made since the kitchen staff said it wasn't a choice. The Rolled Roast beef sandwich was listed under the 2 am choice and they refused to make it untill again, we called the Manager who did get it to us. The staff did appear friendly, although housekeeping totally disregarded our 'do not disturb' sign and would call us on the phone. Don't make the mistake of staying here but if you do, walk across the street and buy snacks you want because even a soda is $3 plus 19% gratuity. We ended up having to order delivery food brought to us. This is the most overpriced, over rated and dingy hotel we've ever stayed in. Taxi to airport is $40.
