Am currently at the Hilton Mag Mile Suites. The hotel has opened an executive lounge on the 2nd floor, hours 6am - 8pm. Seating is available at tables and at counters along the wall facing the windows. A breakfast buffet(scrambled eggs, bacon, sausage, hash browns, fruit, etc) is served from 630a - 1030a. You can also use your breakfast coupon at the Blenz (Starbucks) snack/coffee bar in the lobby. Alcoholic beverages are available for purchase from 500p - 8p and hors d'oeuvres are served from 500p - 7p.
The hotel still has two restaurants Misaki and "The LOCAL Chicago".
I've had a bad stay or two here in the past (the front desk manager has been very forthcoming in recognizing their deficiencies) and overall the property seems to be improving.
