By the way, if you haven't tried 滷肉飯 (lǔròu fàn, or braised pork with rice), you should. You can't walk more than a block in Taipei without finding it, but I've seen it only once in the US.
You will find restaurants with it in LA, SF, and NY for sure. In SF there is an award winning restaurant named Lu Rou Fan, which should give you an idea of the food they serve.
I imagine any region with a large Taiwanese or Chinese population will have a restaurant that serves it (or the chinese version gai fan).
