Chefs have only been able to work in restaurants, high-end cuisine. Why? Why haven't they been able to find other scenarios? For those chefs who want to do avant-garde cuisine, should they be finding their income in a restaurant? These are the kind of questions we are asking ourselves. So the new scenario will allow them to do whatever they want to do, whenever they want to do it.

I don't have a favorite cooking tool. In the kitchen, I always have my pencil and notebook in my hand. I cook more theoretically than I do practically. My job is creative, and in the kitchen, the biggest part of my creativity is theoretical. The pencil has a symbolic meaning for me. The type of person who carries a pencil around is the type of person who's open to change. Someone who walks around with a pen isn't; he's the opposite.

We need to think about what cooking is, what context it takes place in and what its relationship to the world of art is. If there were criticisms of my presence at Documenta, that's a good thing because it means we were doing something new. Your mission in creating something artistic is to produce something new and polemical.

We knew the time would come that we'd have to step down because we'd been winning Oscars for 15 years. I discovered this one day when I got home, my mother was reading a newspaper and she said, 'Again? What are you doing in the papers?' And I realized if my mother thought that of me, what would my enemies think?

In more day-to-day restaurants, things have undergone a seismic change towards informality and sharing, which has been years in the making. Nowadays, people don't want just one dish; they want to order lots of things and they want to do it in fun places, places that give them an experience. The experience that a restaurant needs to offer is no longer just based around the food.

Friends are really important, especially when you've had the successes that I've had. I've gone really far in my career, so they're the ones that keep you humble, keep your feet on the ground.

Could you imagine people eating a painting - if they could introduce a painting into their bodies? It's probably the artist's dream, and we have the opportunity to do so.
