Best Dim Sum in Hong Kong

I'll be going to Hong Kong for the first time in the fall, and am hoping someone might point me in the direction of one of the better (best?) dim sum restaurants in the city. I'm particularly interested in knowing if there is a restaurant that offers an extremely wide selection of dishes, since I'd ideally like to sample things I can't easily get anywhere else (I like har gow, siu mai, etc., but I want to find new and creative offerings).

I don't care a jot about ambiance, old world charm, language issues, cleanliness of the washrooms, or service (as long as it's not so atrocious, it gets in the way of enjoyment) - it's all about the food for me.

Thanks for any suggestions!
