Imelda Marcos has her own way of doing things. It may not seem good form, but that never stopped her before. So she invited the 12 jurors who acquitted her on fraud and conspiracy charges to her apartment for a thank-you lunch, and most of them came. They came with spouses, children and friends to Marcos's posh Second Avenue apartment in Manhattan on Saturday for a dinner of two roast pigs and 14 purple coconut cakes decorated with palm trees and tiny reproductions of the Statue of Liberty. And as at her earlier victory celebration, belly dancers entertained. Joining the former Philippine First Lady was her also-acquitted codefendant Adnan Khashoggi. All this could start an unusual precedent: parties for juries that acquit, nothing for those who convict. There was a report yesterday that Marcos has been ordered to face a grand jury on another criminal proceeding; her subpoena does not indicate whether she is the target of that investigation.

President Bush stopped by to visit his party chairman, Lee Atwater, yesterday as Bush was returning from a weekend at Camp David. The president was greeted at the door of the Northwest Washington home of the Republican National Committee chairman by Atwater's wife, Sally, and their 3-month-old daughter, Sally Theodosia. Atwater, who has been battling a brain tumor, collapsed during a speech in March and until last week spent very little time at his Capitol Hill office. Bush, who was accompanied by his son, Marvin Bush, said nothing to reporters who inquired about Atwater's condition ...

Democratic National Committee Chairman Ron Brown has officially announced that New York City will be the site of the 1992 national convention, but it hasn't been the party's favorite city over the years. The Democrats have met there four times, but according to Congressional Quarterly, the city that has hosted the most Democratic Party conventions is Chicago, with 10. The last one there, however, was the disastrous 1968 convention. The second most frequent convention site is Baltimore, where the Democrats have met nine times, but the last was in 1912. The Republicans like Chicago even better, having been there 14 times. The GOP's second-favorite city is Philadelphia, with 5 conventions ...

Those persistent People for the Ethical Treatment of Animals can claim another victory. The organization has received a letter from Merv Griffin Enterprises stating that fur coats will no longer be given as prizes on television's "Wheel of Fortune." The syndicated show had a policy of using only ranch-raised furs, but Griffin Enterprises President Robert Murphy told PETA that as of April, all fur gifts have been eliminated, although reruns may still show furs given away ...

Tom Cruise has been named 1990's "sexiest man alive" by People magazine, which modestly presents the award each year. It will probably be a big help to the actor's new film, "Days of Thunder." Cruise follows Sean Connery, who took the honors last year, and John F. Kennedy Jr., winner the previous year ...

Rick London, founder of Scandal Tours, the different tour bus look at Washington that takes visitors to some of the spots Washingtonians would like to forget (like the Tidal Basin, where Wilbur Mills and Fanne Foxe took a dip), is making television history of a sort this weekend: He is to be the first contestant on the revival of the old show "To Tell the Truth." The new show's panelists, Betty White, Kitty Carlisle, Cindy Adams and Morton Downey Jr., will try to guess which guest is the founder of Scandal Tours. The show is to air in September ...

Watergate conspirator G. Gordon Liddy was bothered by not being invited to Thursday's opening of the Richard Nixon Library in Yorba Linda, Calif. But he said he completely understood why John Dean wasn't invited: "Would you invite a rattlesnake to sleep in your bed?" ...
