Former Bears quarterback Jay Cutler and his wife, jewelry designer Kristin Cavallari, dined at Siena Tavern, which is where they filmed a storyline for “Very Cavallari” in the fall. They were in town to meet fans at Cavallari’s Uncommon James store in the West Loop. Attendees paid $200 to watch Cavallari and Cutler — who wore loafers without socks on Chicago’s coldest day of the year — answer questions from the audience while sitting on a swing in the store.
