The Wonder Chef sidequest in Tales of Symphonia.
All throughout the game, you could examine out of place objects, and a mysterious man would appear, calling himself 'the Mysterious Gourmet, the Wonder Chef'. He apparently appears to a lot of people, as his legend is spoken in many places. He would give you food recipes which you used to heal your dudes. If you found all of them, you could train in them, and upgrade your level of cooking them. Once you'd trained all of them to max with a specific character, having collected them all, you could find the Wonder Chef in a plaza in one of the cities, and challenge him to a cook off. You win, and get the title; "Wonder Chef", for the specific character. With some amusing dialogue besides.
