Why yes I have. Year 8 French class, my friend and I both ate garlic snails. Don't taste as bad as you think.
My parents are making snails.. For real.. I can send a link to the company if you want to. lel. (It's all in Lithuanian. xD)
Well, I don't really know the "Real" snail taste, but it's with some sauces and stuff, so it's really delicious for me at least.
