In my early days, I copied the great French chefs, like most chefs do. Copying is not bad. Copying and not recognizing that you are copying is bad. For me, when I go to a restaurant and am served a dish influenced by something we created at elBulli, if it's well done, it makes me extremely happy.

If I don't have pressure, I don't function.

I don't do my mother's cooking. Because I am a professional and she isn't. Even if she is a better cook.

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.

You can see it on the Internet now. New society demands that people share their knowledge. It's asking multimillionaires to share their money and creative people to share their creativity. Whoever doesn't share their wealth, be it knowledge, money, or creativity, will be dead.

When you talk about avant-garde cuisine, the surprise factor is really important. For example, I love looking at blogs and the photos, but I'm not that keen on other people taking photos of my dishes.

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.
