Honestly don't see the problem with it. The snake didn't go to waste, and that is all that counts. If I ever saw something like that on a menu, I would certainly try it at least once.
In regards to the python hunt in South Florida, I wish they would let the local restaurants cook em up. At least then they wouldn't go to waste.
Think about it.
There are lots of people with fish tanks that love to eat fish.
There are lots of people who have pet pigs that love to eat pork
There are lots of people who have pet lizards that love to eat gator tail.
There are lots of people with pet birds that love to eat chicken.
There are lots of people with pet turtles that still love turtle soup.
Why should snakes be any different?
