Japan/What happens when a person walks in a
What happens when a person walks in a restaurant and says that he will try any Japanese food, but will never eat whale and dolphin meat? He has a very negative opinion of hunting whales and dolphins because of https://en.wikipedia.org/wiki/The_Cove_(film) and https://en.wikipedia.org/wiki/Whale_Wars He also says that he is thankful that it is illegal to import whale and dolphin meat in the United States.
You'd actually find it pretty difficult to find a place that servers either. Most don't.
At any rate, Japanese foods serve a wide variety of foods, and even for seafood places there is a huge variety of fish to choose from.
So you can eat what you like.
