Assuming that it could be legally sourced and a species that was sustainably harvested, I would certainly try it, even though I eat considerably less meat these days than in the past.
But I do enjoy trying exotic foods, and I've heard that whale is pretty tasty.
In any case, in reality I guess a whale steak would be no more odd or unusual than a lot of the stuff I grew up eating in a household with two generations of Eastern Europeans that consumed animals head-to-tail.
