The training of an 18 years old girl "KOENJI hikaru" starts in one of the major burger shops. By lapping over the materials following the recipe, a "yummy" burger is ready. The recipe becomes more abundant as the stage goes up.
Her zeal to cuisine sees no end. She went to the US to learn about the best dish. One day, she ate a taco for the first time. "I want to know more about tacos." She decided to work in the shop without a second thought.
