The wolf strolled into the bar at Villetta Barrea, near to the Abruzzo national park, and helped itself to a steak sandwich from a table.
Bar owner Giacinto Lorenzo, 43, said: "It sounds like the start of a bad joke, but it really happened.
"Everyone here knows what a wolf looks like and there was no mistaking this beast for a big dog. It was one of the wolves from the national park.
"It looked pretty thin and we guess it must have been suffering with the recent cold weather and the snow.
"Everyone was so frightened we couldn't move for about five minutes afterwards, but the wolf just sauntered out as if it was the most normal thing in the world."
Local authorities have sent a team out to search for the wolf. (Ananova.com)
