The hotel was so amazing for us. Staff was accommodating and helped us immensely. The restaurant for breakfast and the roof top wil keep you coming back. We will try to stay there as much as we can while in Chicago.. Lester and Luis at the restaurants need a bonus. They kept the breakfast crowd well organized.
