The title says it all.  I'm heading there soon and wouldn't mind a few suggestions.  Thanks!

Everybody will bug the crap out of you - "have you been to the peak yet?"

"Welcome to Hong Kong - have you been to the peak yet?"

"Your table with be ready in a moment - have you been to the peak yet?"

"This suit can be picked up in a few hours - after you get back from the peak"

So - If the weather is clear -

Go to the Peak -
