Yes I have been to HK a number of times and I am going there again on my way to Adelaide at the end of this month. I find it an enchanting place where East meets West. I have seen live frogs decapitated in markets with meat cleavers, but I think you have to accept that it is a different way of life.
If you like Chinese food then it is the best place on earth. Just look away if you see something you don't like (which will in all honesty be quite rare).
