Joined by a group of friends, Gaga and the Chicago Fire actor stopped into RPM Italian – owned by Bill and Giuliana Rancic – for some homestyle fare.
The group ordered up dishes including lobster caprese, insalata bianca, duck agnolotti, Sicilian pork arrosti, Mediterranean octopus, Mama DePandi's bucatini pomorodo and short rib pappardelle among others.
The crew finished off their meal with a variety of desserts, but the sweetness continued as the night went on.
"[Lady Gaga and Taylor] were very affectionate and touchy sitting next to each other," an onlooker tells PEOPLE. "I heard her call him 'honey.' "
While it was Gaga's second time visiting the eatery in the past few weeks, Giuliana couldn't help but gripe that she's missed the Born This Way singer on both occasions.
"Bill saw her last time. I'm 0/0 :((," she Tweeted on Wednesday.
