9th February 2016 ~ The place is called Alun Alun, somewhere very near to the Kraton with the two huge "Beringin" trees. This is the place people in Jogjakarta go to at night to get some simple entertainment. Although kids would love this kind of ride in a beautifully modified bikes decorated with colourful lights, adults would enjoy themselves. I think you could "drive" this vehicle with your friends as the passengers.
We did not try the ride though. All the pictures were taken from inside the car.
But now I know an option of what to do in Jogjakarta when the evening gets dull.
