Tuna has been a problem for a number of years. Hadn't heard about whale but I guess that would depend on the waters they come from. El T it's eaten cooked, and I too have had reindeer and that's lovely too. Glid, unlike the Japanese I think the Norwegians are very careful not too over exploit the whale population which means its very difficult to get whale to eat.
Branson Beans for me Slightly more unusual things I've eaten include goat, kudu, scorpion tails & mealworm
