Aloft City Centre Chicago
The F&B Operations as of November 2 or 3, 2013 are under the operational arm of "Lettuce Entertainment" a very long-standing gorilla of Chicagoland. They operate separately and do NOT allow charges to the hotel, not even a simple whisky nightcap. So unless THAT has changed since 2 months, I suppose that this is the most current operation.
I do not recommend this hotel for many reasons, this is just an aside to my recommendation. I actually like to be able to sleep through the night in my hotel, city centre or not.
