Anyone know what natto tastes like?

it's a little bit salty, and has a tiny bitter aftertaste (for me) but I actually didn't like it at first it, I like it better with japanese mayo. I can say that it's worth a try? ^w^

I can only remember that it was kinda slimy and tasted like algae. I personally did not like it. supposedly its healthy tho. ╮(￣▽￣)╭
