Chef Kawasaki's friend Chef Nagoya comes to town. The two chefs compare the flavor of their cooking, and the Cappies like Nagoya's food more. Kawasaki and Nagoya then get in a fight over who Kawasaki's restaurant should belong to, but then King Dedede comes up with a solution.
He holds a cooking contest to determine who will keep the restaurant and who will leave town. Tiff helps Kawasaki prepare food while Nagoya creates gourmet meals with NME-purchased ingredients. When the dishes are served, however, the lights turn off and Escargoon sabotages Kawasaki's entries with very potent spices. After two blackouts, Chef Nagoya catches on and notices a sabotage occur. Though he's named the winner, he announces that Escargoon cheated, and he uses the spice in one last dish, forcing Dedede to eat it.
Unfortunately, this dish transforms into the monsterEbifryer after the king takes a bite. This monster comes after Kirby and swats him with its large claws. Tiff tosses Kirby a ladle, he inhales it, and becomes Cook Kirby. Ebifryer's own fire breath is the end of him, as Cook Kirby's frying pan reflects it into its face. The monster explodes shortly after.
Chef Nagoya later leaves Cappy Town and lets Kawasaki keep the restaurant.
