Adjacent to the restaurant is a replica of the grass house that Robert Louis Stevenson occupied in 1889 when he visited Princess Kaʻiulani and her father Archibald Scott Cleghorn at their ʻĀinahau estate in Waikiki.

[2][3] Located in Mānoa Valley, the Waiʻoli Tea Room was formally dedicated in 1922, as part of the Salvation Army Girls' Home program to teach young women marketable job skills.

It was designed by Emory & Webb, a successful Honolulu architectural firm of the era, to harmonize with nearby residences.

A 1926 addition created a U-shaped building; the resulting interior open lānai was subsequently roofed over and enclosed.

[10] Located on the Waiʻoli grounds adjacent to the restaurant is what has become known as the Robert Louis Stevenson Memorial Grass House.

The structure was built as a guest house at their ʻĀinahau estate by the father of Princess Ka'iulani, businessman Archibald Scott Cleghorn.

When Cleghorn died in 1910, he willed the estate to the Territory of Hawaii, specifying it be maintained as a park in Ka'iulani's memory.
