Chicago bar owner Michael Johnson left the auction house Saturday proudly carrying five pairs of worn tennis shoes and a pair of worn work boots he got for a bargain $160 bid. He promptly hung the shoes, which once belonged to comedian John Belushi, like mobiles inside his bar.

"That's a lot of John for the room for a reasonable price," said Christine Palmer, bartender at McNeil's, Johnson's establishment. Johnson and Palmer were among 200 loyal fans and collectors who attended the John Belushi Memorial Auction at Leslie Hindman Auctioneers and walked away with a smile and something once worn, used or owned by the late actor, best known for his many roles on TV's "Saturday Night Live" and the film "The Blues Brothers." In all, more than $100,000 was raised through the sale of clothing, guitars and other miscellany pulled from boxes in the basement of Belushi's widow, Judy Jacklin Belushi. The auction was to benefit the John Belushi Memorial Foundation, which will help aspiring actors in Chicago. Recuperation and Romance

Elizabeth Taylor underwent an abdominal biopsy yesterday, and doctors detected no new lung infection in the actress, a spokeswoman said. Taylor, 58, is fighting severe depression in addition to recovering from a near-fatal bout with pneumonia, and has decided to make public her romance with a 23-year-old man so he can be at her side, spokeswoman Lisa Flowers told the Associated Press. Flowers said the actress is expected to leave St. John's Hospital and Health Center within two weeks. When she does she will be accompanied by Julian Lee Hobbs of Detroit, whom she has been seeing since 1988, Flowers said. The two will spend a short time at the actress's Bel-Air home before traveling to Switzerland for an extended rest, Flowers said. "She is very depressed. It's a very sad situation," said Flowers. "Julian was out of the picture for so long, and now he is back in. She is blooming again, like a rose." One of Charlie's Angels Flies East

Actress Kate Jackson has quietly left Los Angeles for a farm in Keswick, Va., south of Charlottesville, and put her Benedict Canyon home up for sale, the Los Angeles Times reported yesterday.

Zsa Zsa Gabor rallied her celebrity friends for a charity auction Saturday, even though a judge told her it wouldn't count toward her 180-hour community service sentence. Clad in a pink Christian Dior outfit, Gabor reigned at the glitzy Beverly Hilton gala where items up for bid included one of her emerald necklaces, an autographed book from Bob Hope, a Phyllis Diller self-portrait, a Bob Mackie gown and a Tennessee walking horse. Auction proceeds will go to the shelter for homeless women where Gabor, who was found guilty last year of slapping a Beverly Hills cop, must do her community service. The actress said Saturday she's abandoning her appeal of her three-day jail term and will report for lockup next month. "I don't even want him to know me any more," Gabor said of Municipal Judge Charles Rubin. "I'm going to jail for him and work another 95 hours for him, and then I'm going to say, 'Goodbye, dear judge.' " Maternity Report

The Presidential Catch

Vacationing at Camp David, President Bush had his share of fisherman's luck Saturday, reeling in 10 largemouth bass from a private pond near the presidential retreat.

"He did real well," said Bush's fishing guide, Robert W. Abraham of Smithsburg, Md., owner of the quarter-acre pond where he and Bush went fishing. White House spokesman John Herrick said Bush threw back all the bass, which ranged from eight inches to a foot in length.
