Bambino! (2007)

both dramas are based on food

Both are great Japanese dramas that centers around food. Both dramas also have great comedy and bit of romance mixed in. They are dramas that makes you hungry.

Both closely follow men (Both from Johnny's Arashi)as they try to become the best in their field.

Both are dramas that handles food theme. Both has funny situations in Italian restaurant.

Both tells the story of a talented chef and their work life in a restaurant. The differences are in 'Dinner', the main character is a chef who once works in a prominent restaurant in Italy while in 'Bambino', the main character just about to learn the harsh world of being a chef.

Both are about Italian restaurants, and there are lots of cooking scenes that make you hungry. The main plots are different (Dinner is about saving the restaurant, while Bambino! is more like a coming-of-age drama about character growth), but they have the same simple, heartwarming atmosphere that makes you smile.

Takeshi, an Italian restaurant chef, and Ruri could have been lovers, but Takeshi was too comfortable with their current relationship that he chose to stay best friends with her. Now, Ruri is engaged to another man and Takeshi is deep in regret. He runs through the night of Tokyo to tell her his true feelings before it's too late, but right as he stands in front of Ruri, an unfortunate accident takes his life away. However, a twist of fate brings them back together once again in an ironic situation. "Eternal First Love" unfolds as a bittersweet story of an everlasting "first love."
