There's certainly been a lot more tv series and movies centered around cooking and restaurants, such as Ratatouille, No Reservations, and the show that only made it to the 1st season, Kitchen Confidential.
While this is really great, let's not forget that there has been a lot of entertainment materials centered around cooking from other countries. For example, the Japanese has put out a lot of films, tv drama, and anime about chefs. One that I have recently watched is My Little Chef:About the daughter of a once famous chef, her half sister, and other friends, they attempt to operate a high class French restaurant who serves a small number of guests each night, preparing dishes that are meant just for those guests.
As with other J-dramas, there are a lot of cheesiness in all the episodes, but the dishes sure look good! :D This is one of the better cooking dramas out there, unlike certain ones that are way too cheesy even for food lovers. My Little Chef still has a good story line and executed within acceptable bounds of reality :>
