I came across the following descriptions about Garive's Rooms, the first cinema to operate in Nairobi!!
Kenya's first Cinema
Donald Sutherland Garvie (3 June 1873 – 22 October 1912) was a pioneer European settler in Kenya. In 1909, he opened Garvie's Bioscope in Nairobi, the first movie theatre in Kenya source: https://en.wikipedia.org/wiki/Donald_Garvie
Donald Garvie, a Scotsman, began new ventures. He opened a a picture house or Bioscope, known as ‘Garvie’s Rooms,’ opposite Madame Rowe et Cie in Government Road, Nairobi. This was sometime after 1907. It showed entertainment every evening at 9 pm. The program was changed twice a week, and on Wednesdays there was a matinee for children; the cost was 3 rupees a chair, and half price for children. Donald’s youngest brother George often played the pianola during performances and his daughters Dolly and Louise were fine singers who took part in Nairobi concerts. If the quality at the Bioscope was poor, there were jeers from the audience and bottles would rain down on the tin roof of the Travellers’ Club next door. Garvie also edited the Nairobi newspaper The Advertiser
At Garvey's Rooms in Government Road, on hard wooden seats, Europeans could enjoy shadow play and music-hall acts, smoking concerts and amateur theatricals.

"Although amateur theatricals were the mainstay of pre-war entertainment, celluloid had made its debut thanks to J.Garvie (sic). If films were little more than flickering shadows thrown across a screen, many paid to sit on wooden forms at Garvie's Rooms to watch them. When the quality was very bad, the performance was interspersed by jeers as disapproving members of the Travellers' Club nearby threw empty bottles and more vulgar things on to the tin roof of the little theatre." - Errol Trzebinski, The Kenya Pioneers.
