The Washington Post contains an article on a recent survey by Oklahoma State University where over 80 percent of Americans support “mandatory labels on foods containing DNA,”
The Oklahoma State survey result is probably an example of the intersection between scientific ignorance and political ignorance, both of which are widespread.The most obvious explanation for the data is that most of these people don’t really understand what DNA is, and don’t realize that it is contained in almost all food. When they read that a strange substance called “DNA” might be included in their food, they might suspect that this is some dangerous chemical inserted by greedy corporations for their own nefarious purposes.
The article discusses the wider issue of scientific ignorance driving policy decisions, and there is some further comment at io9. A summary of the full survey results is available (PDF).

I'm heavily into cooking. I've always thought it would be cool to operate my own restaurant.
Catering might be a good stepping stone. You have a limited menu, set dates to plan for, do not have to deal with the restaurant stuff, and the initial investment is not as high.
I would recommend buying an immersion circulator if you do not already have one and like to cook.
