Denny’s restaurants across North America were jammed Tuesday with patrons hungry to take advantage of the restaurant chain’s Grand Slam breakfast giveaway.

Denny’s announced in a commercial Sunday during the Super Bowl that it would give away its signature breakfast from 6 a.m. until 2 p.m. local time Tuesday at all its restaurants in the U.S., Canada and Puerto Rico.

Media outlets reported customers lined up outside the doors of many of Denny’s 1,500 locations.

Some patrons were still wearing their pajamas and slippers, and strangers were crowding together into booths, CNN affiliate KSL-TV in Salt Lake City, Utah, reported.

“You couldn’t beat it. I mean it was a beautiful, beautiful breakfast. It was fit for a queen or a king,” diner Annah Shoffner told CNN affiliate WNCN-TV in Raleigh, North Carolina.

“To do this is amazing and not something you hear of every day, especially in today’s economy — that we’re getting something free,” Debbie Brugger of Essex Junction, Vermont, anticipating a hearty breakfast at a Denny’s in Burlington, told CNN affiliate WCAX-TV
