(CHICAGO) -- Ashton Kutcher and girlfriend Mila Kunis spent time together over the holidays in his hometown of Cedar Rapids, Iowa, but they've since moved on to the Windy City.
The former That '70s Show co-stars were spotted on a visit to Chicago on Thursday, an onlooker tells People. The couple was spotted around noon at eco-friendly restaurant Prasino.
The witness says, "They were both very courteous to the staff and flirtatious with each other."
The lovestruck stars apparently dined on the short rib skillet and Florentine crepes.
