On a busy day the lobby of this Hilton might be mistaken for a terminal at O'Hare Airport; it's a bustling convention hotel, but one that retains its distinguished 1920s heritage in a Renaissance-inspired entrance hall and gold-and-gilt grand ballroom. Renovations completed in 2012 provide new dining and drinking options—the venerable Kitty O'Shea's bar remains—and a more modern feel for 454 guest rooms. The gym, at 28,000 square feet, has enough room for an indoor
track and swimming pool. Nearly 200 rooms have access to an executive lounge for complimentary breakfast and evening snacks.
