Oprah threw the most star-studded party of the year at the Four Seasons after her second-to-last show, so how did she celebrate the taping of her very last one? Considering that the final episode was much more subdued than the United Center blowout, it makes sense that she chose to mark the occasion by dining in the private space at Spiaggia. We mean, isn't it the official spot for Chicago royalty? According to our source, only 18 people were allowed in, including Steadman Graham, Gayle King, and Maria Shriver. Chef Tony Mantuano was on hand to greet the guests when they arrived. The group ate a four-course dinner, which included a gnocchi with black truffle sauce dish.
