Some Braised Whole Shark Fin for lunch?

It's hard for me to fathom that people consume ANY shark fin products, let alone the huge quantity that they do. Even in the US. I noticed this menu on a restaurant in Honolulu a couple of weeks ago:



There was a guy out in front of the place who obviously worked there. I said something about the shark fin soup and he replied in stilted english that it was very good and I replied that it was very bad. He was very puzzled. I tried to explain but it was of little use.

And what's up with the "live sunfish".

It's probably a good thing I didn't go inside.
