Sekko, a restaurant in Tokyo, is selling shaved ice made with natto — or that fermented soy bean that's pungent, gooey, and stringy (all at the same time). The dish is topped with sweet soybean flour and brown sugar syrup, resulting in something that kind of looks like excrement that's been left to dry. But that's okay: Rocket 24 promises it actually tastes pretty good. Then again, how good can something based on what is essentially sweetened, rotten goo really taste? 800 yen ($7.90 USD).
