Harry took part in several workshops while visiting the charity, which his mother visited in 1991, and unveiled a commemorative plaque to mark the project's 30th birthday.
The red-headed royal also helped kitchen staff serve meals to service workers and volunteers, who provide information, advice, support and advocacy services for people living with or affected by HIV.
At one point, Harry sweetly walked by a black-and-white photo of his mother that hung on a wall.
