Hong Kong IS organized chaos. It's a hilly, efficient, and eclectic city with all the amenities you could hope for all boiled in a Chinese mixing pot. It's good. Really good. I've been describing it as a world city for all these reasons to all those who ask what my opinion on the place is. Halloween a few days ago was the epitome of organized chaos, with the whole downtown area completely congested by decorated and costumed foot traffic, and the police making the most popular areas a one way for said party-goers to ensure nothing like what happened a few years ago happens again, when some participants were trampled to death by the sheer mass of the surging crowd literally plowing over their bodies.
I also went to Macau, one of the strangest culture mashes I have ever seen - it's a Portugese colonial area of China (now a S.A.R. like HK), meaning it LOOKS like Europe in so many ways, with brightly coloured, slightly decaying buildings, mosaic tiled streets, and portugese foods at hand, but the people are most definitely Asian. It's as if they were supplanted into an area not their own. I loved it; it's not like anything else I've seen anywhere in the parts of Asia I've trekked through. Not just the culture mash did it either - it's also been set up to be Asias answer to Las Vegas of all things, with gaudy, towering casinos blaring their expectedly bright lights. The handy thing here is that even though they have their own currency; the Macau Patacas; they readily accept the Hong Kong dollar everywhere, which is handily currently right on par with the local currency.
