It's not that unusual that the ethnic areas are in the suburbs. The current immigration laws basically shut out people without some college education. The exception is refugees, who can be of any class. Consequently, most immigrants to the US don't have a good reason to live in the city.
It seems that the cities tend to attract "city people" and people who can't handle the expense of living in the burbs.
I believe that the Metropolitan Hotel and adjacent shopping center were built by Indonesians perhaps 10 to 15 years ago (on Sunset Bl. right by the Hollywood Fwy. offramp), and that there were Indonesian restaurants in the shopping center. I'm not sure if the Indonesian character has survived.
The Metropolitan Hotel was definitely built by Indonesians, but the Indonesian character of the surrounding minimall seems to have evaporated.
I could be wrong, but basically the county's Indonesian population is prety dispersed. There was a big expat presence at USC (which suddenly dispersed with the crash of the currency a few years ago), with a couple of cheap restaurants in the Vermont corridor to serve them; and a similar pocket south of UCLA. A population pocket remains in the Artesia/Bellflower area -- which was a pretty heavily Dutch dairy-farming district before development claimed it in the '60s -- and the biggest groceries are down there. There are smaller pockets in Inglewood, the San Gabriel Valley and Van Nuys.
But nowhere, I think, will you find a strip with as many as three or four Indonesian businesses in a row.
Here is a list of Indonesian restaurants in SoCal I found on a site called www.hollandring.com
