HK , looks like LEGO, the toy who child played. because it created by many many tall buildings, I guess over 40 floors height.almost such building around.
Dont worry this issue.
The streets in Hong Kong, just only 2 cars wide and every streets close each other.
People there almost can conversation with English, because they were the British before 1997.
Hong Kong is not so big, so the people almost sit the same table to eat in restaurant together with strangers. It is usual thing there. If you can not accpet, you can pay more to the more high quilty restaurant. But to be honest, the most tradition and delicious food almost comes from such local restaurant.
