I actually missed this movie myself, until I heard the Nerdist podcast where Jon Favreau (Iron Man, Iron Man 2, Elf) was being interviewed about his experience directing this film. He also plays the main character, a chef who is struggling in his field and as a father. Chef is a feel-good heart-warming sort of movie. Honestly, we don't get many of these anymore, which is sad, because it is a truly fun movie about a relationship between a father and son. I never really thought about how rare of a movie this is until I found myself waiting for something crazy and tragic to happen.
Chef is what I would call a family comedy, based around a prestigious chef who is a legend, but isn't appreciated by the owner of the restaurant in which he works. A food critic pays a visit to the restaurant, and dissatisfied with the menu, posts a bad review of the restaurant on his blog. This takes Chef Casper on a social media filled tailspin where he learns about the power of Twitter through his son, who teaches him how valuable the internet is to business these days. Without spoiling the film, they use this "bad review" as a springboard into a journey that brings the father and son closer together.
It's a fun movie, and one that will certainly make you hungry. They do an amazing job creating and cooking delicious looking meals at the hands of Chef Casper. It's all believable, and there are some pretty big cameoed celebrities like Scarlett Johansson and Robert Downey Jr. along the way. (Not surprising since they worked with Favreau in the Iron Man movies)
Bottom line, the movie is just fun and good. It's rare to find a movie that isn't a gritty look into a relationship, but rather it's filled with hope and good food.
