Very nice festival that is not advertised hence not many non-Indonesians attend. Very nice grounds, plenty of shade in lush forest. Harder parking since it is in the neighborhood. You can tour tour the house on the grounds (residence of the ambassador) and see some impressive Indonesian master craft - in wood.
There are plenty of exotic drinks and food. Nothing strange, good BBQ with Asian spices.
There is no alcohol because (as far as I learned) Indonesia is predominately Muslim (86%) and secular in its nature.
There are at least 20 food vendors so people who have hard times making their minds up may have hard time.
Good entertainment program - ethnic music and dance.
I visited it 2 times and had great time both times.
I recommend visiting great Hillwood Museum and gardens that is only 6 minute walk from there read more
