The Queen of Lunch (2002)

Natsumi loves lunch. By chance she starts working for "Kitchen Macaroni", posing as the fiance of the owner's eldest son, Kenichiro. Kenichiro's father Kenzo and his three younger brothers - Yujiro, Junzaburo, and Koshiro - run the restaurant, famous for its omelet. Also working at the restaurant are Mamoru, a chef, and Minoru, a live-in apprentice cook. Not everyone has a liking to Natsumi at first, but over time they will surely fall in love with her.
