My son and I have had lion fish - but it is hard to find even in the best seafood restaurants - and very expensive. It is VERY good! It was not been available after the last hurricane season because the waters were so stirred up it made catching them too dangerous.
On my last dive trip to the Caribbean we hunted them with a vengeance. Lion fish is one of the best tasting fish out there, broiled or grilled. We would hold them down with our Hawaiian slings (that’s a type of spear) and someone would cut the spines off with surgical scissors.
