Bogor is not a big city. But have a tea-break or hang-out with friends waiting the nightfall is cool. One of my fave place here is Kapulasan Cafe --which we can walk and seeing the gallery in between drink tea or cappuccino. This place also nearby Pia Apple Pie.

NIGHT LIFE? It does exist in the form of music and dance and disco in one or two locations. Ask locally about which places are protected by the strongest faction of the army.
Fighting among army/police factions is not unknown. Go with an Indonesian if possible. Crime has been rising in Indonesia. But, most of the time you will be safer than in the UK. In most neighbourhoods, the local people keep an eye on each other and stamp hard on troublemakers. Persistent criminals sometimes get beaten up and killed. Most crime is committed by members of the armed forces, the same people that allegedly run the various rackets.
