I don't think eating meat has much to do with building muscle lol. Sure tigers have lots of muscle, but so do deer. A deer is all muscle. That's why they run so fast. Most wild animals are muscle. If you ever eat deer, elk, rabbit or most wild game, it's all meat, almost no fat. Humans are the fattest fucks on the planet because we've become so physically lazy and pathetic. And the animals we eat from farms are unnaturally fat. Fish is actually kinda fat, probably because they need to stay warm in cold water. Animals like seals, polar bears, whales, etc. can be quite fat. It's mostly to do with genetics and lifestyle. But I do like the restaurant idea hah.
