This is the mainstay spot if you visit De Karanganjar. OG Cafe stands for "Ons Grootouders Cafe" which in Dutch means "Our Grandparents' Cafe". This cafe, which used to be a coffee storage warehouse, serves various variants of coffee brews and also a variety of Western-Indonesian food blends. Various vintage furniture and music from old times really seem to bring visitors back to the passage of time. If you are lucky, you will be served by foreign waitresses who are apprentices from abroad. This is a uniqueness that can only be found in this cafe.
