A diner at the Plainfield Road Steak n' Shake was gravely injured and permanently disabled when he drank a milkshake contaminated by "foreign matter," according to a lawsuit filed in Will County court.

The attorney behind the lawsuit, Adam Gilbert, refused to identify the "foreign matter" supposedly ingested by his client.

"You know what, I really don't have any comment on it right now," Gilbert said before hanging up the phone.
