I am partial to Grouper. I am biased though because my area is a commercial Grouper fishing hub. We get all the freshest Grouper. I have often fantasized about dropping everything and joining the crew of Grouper boat, then I remember that commercial fishing has the 2nd highest occupational death rate in the US, and I'm like ok fuck that.
I had a blackened grouper sandwich at some port side bar in Siesta Key and it still remains as one of the best things I've ever had.
