The 19-year-old model dressed to impress in skinny leather trousers, a long white shirt and monochrome coat as she joined Gigi and pals at Red Stixs on 26 April.
Just two days earlier, the star's father Bruce, 65, opened up on ABC News about his gender transition, confirming ongoing speculation that he wishes to live as a woman.
Kendall did not join Bruce on the interview but, along with sister Kylie, 17, she sent a statement declaring her love for Bruce and support for his decision.
She also tweeted: "I love you. So very proud of you, my hero."
Bruce told Diane Sawyer in his interview: "For all intents and purposes, I'm a woman. People look at me differently. They see you as this macho male, but my heart and my soul and everything that I do in life - it is part of me.
"That female side is part of me. That's who I am."
His transition will continue to be charted in a new E! reality show to air this summer.
