After ordering either a parfait or French toast parfait or cappuccino, you receive the parfait with nothing drawn on the surface, and choose your favorite from 3 types of plates and 7 types of powder (the type of powder will change depending on the season). Powdering can be done on the plate at the dedicated counter to create your own "Yojiko".
After you have finished, take a commemorative photo at the photo spot inside the store. Two doors down is the YOJIYA Shimizu Store, where you can purchase YOJIYA products such as skin care items, so take a look after taking a break at the cafe.
