From one concrete jungle to another, it's shocking how much more dense Hong Kong is than New York. Every last square inch is utilized for something. Efficiencies (which I'm a massive fan of) aside, there's also generally an aesthetic flair and appeal to the efficiency that further lends to a notion of intentional efficiency or perhaps more elegantly put - designed density.

The contrast between new and old is also incredible in it's parallels to New York, skyscrapers stand adjacent to temples (Man Mo Temple - 1847) that date back 200+ years much like One World Trade sits across the street from Trinity church (building1839, history 1696). 

The next amusing parallel is the diversity of cultures, food and people. Most people are Hong Kong locals but there's a fascinating sub culture of other ethnicities that only makes life all the more interesting. In one corner there's a sushi chef importing from Tsukiji everyday, across the street, a taco place (not great but props for trying), a couple blocks down, a Filipino hipster singing Yellowcard and serving up craft beers from New Zealand. Simply stunning.
