The cast of FOX's hit show Glee was in town this weekend to tape an episode of Oprah! Some of the cast members including Mark Salling, Cory Monteith, Harry Shum Jr., and Naya Rivera were spotted having dinner and drinks Saturday night at SushiSamba Rio. They enjoyed maki rolls and shots of chilled Patron. Sounds delish! Also, hit singer Michael Buble was spotted enjoying a late lunch recently at State and Lake restuarant at the Wit Hotel. He was in town for a sold-out performance at the Allstate Arena. Finally, Olympic figure skater Michelle Kwan dined the other day at Mercadito restaurant for dinner with five friends.
