There are many road side food stalls I found near the hotel I stayed in Jakarta city area last week.
Some of these food stalls start their business since early in the morning. However, majority of these food stalls appear in the late afternoon and evening on roadsides, sidewalks and in any open space to provide meals to passers-by. It is not surprise that you may find some of the best food but in cheapest price over here. Anyway, it may lack of good hygiene in the road-side food preparation. So be careful, do watch how the food is prepare
You may enjoy your food here, sitting about half a meter from the road and watching about a thousand cars pass you each minute
