I'm going into a technological art field for the same reason- robots aren't going to be designing games, TV shows, or anything like that any time soon. They can't choose who to film how, but they could come up with a basic plot arc, maybe.
I doubt chefs would completely lose their jobs. Let's look at Ghost In The Shell for a second.
Togusa stayed 100% human in a world full of cyber-brains, cyborgs, and machines. There would surely be people who would want something made 100% by a human, sort of how we have "free range" chickens and stuff like that. There would be moral debates, marketing and slander (Robots are cleaner than humans! Don't worry about sickness! / Cooked exactly as you would cook it!)
Furthermore, you'd have to be careful about menu selection. A robot could cook 100 different kinds of steaks, or one. Many people would eat at the restaurant where there are 100 options on how you want your steak done, however, if they are similar they may grow bored and want something new and go elsewhere, possibly to a human chef. One steak recipe gets old fast.
Governments could have something like Blue Laws, where one day out of every week or a week out of a month or whatever, mechanically prepared food is not sold at certain hours. If employment becomes a problem, something will break- the education system can only go so far, especially since employers never want to train you "waaah, why should we help anyone", so laws mandating an employer train employees for some amount of time may become the norm.
Let me put it this way. Capitalism will die when base labor becomes a robot's job. Capitalism works by having people do things for you- you're thing is special, it gets you money, you make the thing, hiring people who take some of your money, the government takes a fat stack from all of you, everyone makes enough money to live. This is how it works in a vacuum- when you add technological advancement, you destroy the base, meaning everyone has to enter the top rather than as a laborer, which is not possible.
Education will not succeed in getting enough people hire-able. Capitalism prevents people who don't do well in school from ever succeeding- "Why should I train this person? It's MY money."

And becoming a robot isn't going to be cheap, as well as seen as morally bankrupt- this person must be augmented to be accepted into a workforce and they can't afford the augmentation in the first place, so they take out a loan they'll never be able to pay off, because there's too much ability to loanshark in this scenario.
Hell, the only part I want to keep is my right arm. Even then, I'd love to augment it so that I can draw at the tiny-ass scale I can't stop using for some reason exceptionally well, as well as stop shaking all the time when trying to draw at said scale. Would I become mostly mechanical? Yes. Yes I would.
edit edit: guys I get ninjad so much in this thread, like, every time I post it's at least three ninjas. Ninjas must actually be robots sent from the future to guide us on the right path or something.
