Gurdjieff: Cafe de la Paix, perhaps a bit before his time.

via youtube.com

This at least gives a taste of the Cafe de la Paix,
as it was in the 1920's, I am sure Mr. Gurdjieff
would have been at least aware of it at this time.
But at about.51secs in, you get a taste of how
busy it was, and where he did his writing.
