I can't remember where exactly, I think it's when you're following Lisa, but at one point on the Silent Hill streets you pass by a Chinese restaurant called the "Jade Palace"
I'm too lazy to skim through my copy, but I'm pretty sure there's a Chinese restaurant of the same name in Stephen King's IT, which would make sense seeing as how Silent Hill more resembles Maine in this one
also the memory of the drowned boy in the sewers also vaguely reminded me of IT (they float! they all float down here!)
It's called "Jade of the Orient".
It IT the boy ( george, bill's younger brother) doesn't drown. he gets his arm ripped off by pennywise.
Thats how he dies.
There is a scene in which Pennywise appears to Stan Uris in the guise of a boy who drowned in the Standpipe.
