Twenty-six courses, £400 bills, artichoke creme brulee… I won’t miss super-luxe restaurants | Jay Rayner

Top establishments such as Noma are closing. They were fun for a while but we've had our fill

In 2007, for a book on the world's luxury restaurant economy, I undertook what I called the high-end Super Size Me. In the 2004 documentary, Morgan Spurlock ate McDonald's every day for a month to see how it would affect his body. The high-end version involved me eating in a Parisian Michelin three-star restaurant every day for a week. Back then, talking about this stunt felt like a boast; now, it feels like a confession.

I won't pretend it was all terrible. There was an extraordinary pea dish at Restaurant Guy Savoy, which elevated the humble legume to god-tier status; at the tiny L'Astrance, there was the most spectacular chilled tomato soup. But for all these bright spots there were also disasters: langoustines on sticks wrapped in brackish sea-water foam at Ledoyen, an appalling artichoke creme brulee at Le Grand Vefour that was split. But what really stayed with me from my grotesque endurance feat was the unreality of this kind of high-end restaurant: it's grim, preening, massively unenjoyable artifice. And if a meal out isn't enjoyable, what's the point of it? My love affair with the finest of fine dining began to crumble.
