In 1984, when the World's Fair was in New Orleans, I ordered fish at the Filipino restaurant.
I have no idea as to the species of fish but do remember that it was served prepared with a sweet glaze.
I have never before or since had fish prepared in any manner that could even begin to approach that which was served at that amazing meal. Having had many meals during my relatively long life, I would name that meal as the most wonderful food that I have ever had.
