A cup of coffee in Japan's "Burang Avenue" will make you thin

Professional barista exchanges Please pay attention to the coffee workshop (Weixin Official Accounts cafe_style) in a scene like Taitung Bolang Avenue, but I am in Yamagata Prefecture, Japan. This landscape cafe "Cui" located in the field is opened in a seemingly ordinary house, but I can drink the boss's unique black rice coffee. It is said that after the boss drinks it for a long time, he will slim down from a big fat man to a slim figure.
