I will always regret it. The year must have been 2002, perhaps even earlier. I had rented a flat in Barcelona to test recipes for my offal book and was there for 3 weeks. During that time, I could have easily gone to El Bulli whenever I wanted. I had a well-connected friend who would have organised it for me — in fact he had organised an amazing offal dinner at Can Fabes and an exquisite lunch at Ca L’Isidre where the owner gave me their recipe for tripe. But El Bulli was far and I was not so taken by molecular cuisine after a disappointing meal at the Fat Duck. So, I didn’t even try to get a booking. Then it became incredibly difficult to get in and now it is closed. Since then, I decided never to miss eating at a restaurant I was interested in even if it means travelling. Last year I went to Noma and I am just back from Faviken where I had the most amazing dinner followed by a terrific breakfast in the most serene if slightly ascetic atmosphere.
