I found the opposite to be true. It tasted like beef, not bad but far and away the worst beef I've ever had. We tried it as a group in Japan and it only was something approaching delicious when it was extremely thin cut and raw. If it were significantly less expensive than actual beef, I could see it being a viable substitute, but I just never see there being any reason for me to pay for it myself again.
There's more than one kind of whale meat. Just like Wagyu will have a different taste, I expect Iceland and Japan to have different whales. My experience was from Iceland. I'd really like to try the Japanese whale meat but at the same time don't like the idea of eating unsustainable stuff.
