It is a dish available in many places here, and yes, it is as least as good as you think it would be.
Do they do Ramen over there? The Chashu was going to be a thing for my clone of tonkotsu ramen (same website has the recipe for home-made).
I've been getting on a big japanese/chinese kick lately. It just seems healthier, although the Bao I had last night were pork with no vegetables, so that doesn't really count I guess. Nor would this count as healthy, I suppose... Oh well.
