The Connecticut restaurant Mystic Pizza made famous by the Julia Roberts movie of the same name is under investigation by the IRS.

The U.S. Treasury Department seized more than $60,000 from the bank account of restaurant owners John Zelepos, George Zelepos and Christos Zelepos. The seizure of the money was revealed this week in a legal notice published in The Day newspaper in Connecticut.

Members of the Zelepos family did not respond to requests for comment and a representative at the restaurant said they had "no comment" on the matter.

The family owns Mystic Pizza LLC, which encompasses Mystic Pizza in Mystic, Conn., Mystic Pizza II in North Stonington, Conn., and the Mystic Pizza Food Co.

The Mystic Pizza Food Co. sells frozen pizza with the motto "A slice of heaven," the same slogan that was on the t-shirts of Roberts and other actresses who worked at the restaurant in the movie.

Federal authorities confiscated the money in January after a criminal investigation, according to The Day.

Lisa Kennedy, the IRS special agent in charge of the investigation, told ABCNews.com she could not comment on the case.

The legal notice in the newspaper asked that anyone with a claim to the money seized from the account contact Kennedy.

The 1988 film helped launch Roberts' megastar career and her portrayal of Daisy Arujo in the movie is often seen as her breakout role.
