While traveling to Memphis, Tennessee, to attend nightclub entrepreneur and friend Guy Pelly's wedding, William, Duke of Cambridge, 31, made a stop in Chicago where he grabbed a bite at O'Hare International Airport's Terminal 5.
William, who recently celebrated his three-year wedding anniversary with Kate Middleton, enjoyed pulled chicken nachos from Hub 51 and chicken wings from RJ Grunts in a private Swiss Air Lounge.
"A hostess and server from the restaurants took great care of him before he jetted off," says an onlooker.
William will meet up with his brother, Prince Harry, 29, in Memphis on Saturday for Pelly's wedding. Harry passed through Miami for some post-split partying before their pal's big day.
