Dairy Chiko, in the basement of Nakano Broadway, is a surrealist ice cream shop known for octuple-decker soft-serve cones. You can also order a smaller cone with less than one billion calories, but the draw at Dairy Chiko is watching how other people eat their towering cones of vanilla, yuzu, milk tea, matcha, ramune, orange, strawberry, and chocolate (flavors may vary). Walking while eating is taboo in Japan, and Dairy Chiko has no seating area, so people loiter near the stand, two to a cone, drawing spoons up the sides of the ice cream, trying to forestall the inevitable. Old ladies, meanwhile, usually order a small matcha cone and eat it with a spoon, avoiding the shame of a green milk mustache. Near Dairy Chiko is a cafe with a public seating area and a very angry-looking drawing of an eight-layer cone with the international NO symbol superimposed on it.
