Nat Bussichio

Nat Bussichio is a character from the "Beverly Hills, 90210" continuity, introduced in the first show. He is portrayed by actor Joe E. Tata.

Nat is the owner of the Peach Pit diner and often acted as a father figure and a voice of moral support to the entire gang, most notably to Brandon Walsh, who was a loyal employee in the show's early seasons. Nat was also a former actor.

Nat suffered a heart attack during the fourth season, leading to the possibility of the Peach Pit's closing. Brandon sacrificed much of his time to oversee the diner's functioning while Nat recuperated. The Peach Pit was saved when Dylan McKay bought out Nat's cousin's share.

During the sixth season, Nat rekindled his romance with his former girlfriend, Joan Diamond, whom he hadn't seen in over two decades. Joan became pregnant, and she and Nat got engaged. She went into labor in the middle of the wedding ceremony and, at the hospital, insisted on completing the marriage vows before going into the delivery room. She gave birth to Nat's only child, a son named Frankie.

Nat also escorts Donna Martin down the aisle at her wedding to David Silver in the series finale. Donna's father, Dr. John Martin, died of a stroke midway through the final season of the series.

Nat and the Peach Pit have returned in the 2008 spin-off series, "90210".
