There are several CBD in Jakarta, beside Sudirman, Central Jakarta, there are 2 in Kuningan, South Jakarta. There is side walk there and there is free bus as well which circling the areas but we see none in the video since it was captured in 2020 during Pandemic time.BTW Sudirman CBD looks beautiful. Where do people walk and get lunch from? Are the cafeteria's inside the buildings?
Yup there is Cafetaria in my building when I was working in that area, there is also some kind of cheap food restaurant run by micro business outside the office building near my building, still in the CBD complex though.
There is Mushola (Small Mosque inside the building) as well, during Jumah prayer we use parking park for pray, but some office building in Jakarta has dedicated Mosque, like entire or half floor for praying. Government office usually make dedicated Mosques inside their building complex, but it is not difficult to find Mosques in Jakarta. I also see at least one office building in South Jakarta make a real mosque (quite big) near their office building.
