In the 1960s Elizabeth Taylor -——According to one biographer, “She loved not only beluga caviar and champagne but American fare like cheeseburgers, French fries, and of course, chili from Chasen’s.” Her obsession with Chasen’s chili knew no bounds, and she had it flown to her all over the world, most famously to her palatial Roman villa during the filming of Cleopatra.”
Maybe Streisand’s dogs prefer a certain type of food flown to them, too.
