I'm not sure what confusion led to my table here being reserved in the name of 'Terence Jupp', but there was something about the confidence of the staff that made me feel I should go along with it. I myself had got confused about the dress code. I'd read that you could come here looking relaxed, but the term clearly has a different definition in Notting Hill than it does in Southeast London, where I live. I don't mean to suggest that I turned up in slippers and tracksuit bottoms, but as I crossed the floor to my table with my shirt untucked, something about the pristine nature of the place made me feel the most dreadful oik. The other diners - family groups, glamorous couples and the odd mogul -perhaps mindful of the restaurant's two Michelin stars and its new status as one of the 50 best restaurants in the world, were dressed luxuriantly. Fortunately my companion, the actor Tom Hollander, arrived looking smart enough for the both of us. He was also at ease with the wine menu, a catalogue of such rarefied wares it made my hands tremble.
