Iero Roppongi is a cafe in Roppongi, Minato City, Tokyo, that serves bingsu until dawn. Its bingsu includes matcha, tiramisu, mango, and carrot mascarpone, all made with soft, fluffy ice. Customers order one menu item per person and eat at the basement counter and table seats. On a Sunday night at 10 p.m., seven people were in line and waited about 15 minutes, and the basement's damp smell is a drawback.
