They enjoyed steak and seafood at the Bistro 82 eaterie in the suburb of Royal Oak, according to People.com.

A source tells the website, "They looked like a great couple. They paid a lot of attention to each other... Everyone was freaking out in the restaurant. I was star struck."

The couple met on the set of 2003 superhero movie Daredevil and married on 29 June, 2005.
