Overview:

Hinako-chan, the poster girl for an okonomiyaki restaurant, is forced to open the restaurant alone after her father is hospitalized with a strained back!
But when she struggles with sales, a regular customer gives her advice on how to increase sales, leading her to add more naughty items to the menu…
Listen to customers’ orders, prepare the menu in the kitchen without making any mistakes, and serve it to their tables. If you bring them something different from what they ordered, they’ll get angry and leave.
If you don’t reach your daily goal, it’s game over!
