As my companion, I selected a highly cultivated member of a distinguished French family. Halfway through his noisettes d'agneau, he remarked that this was the sort of food he had been served as a child. It is superior, elaborate French nursery food. Bourdin is an anachronism and proud of it. The food here is time-warp stuff, with names such as Oysters 'Christian Dior' and Fillet of Angus Beef 'Aristotle Onasis' (sic). When viewed from a contemporary perspective, the carte is confusingly old-fashioned; mixing the plain, smoked Wiltshire trout and Connaught chicken pie with the blatantly retrospective such as the supremes of teal 'Belle Epoque' and the self-referential Trifle 'Wally Ladd', named after a pastry chef who worked here from the Thirties to the Eighties. Moreover, pricing is steep, verging on the precipitous: Onassis's beef, for two, costs £45 a head, roast turbot the same, the Queen's lobster sneaks in just under £40, while a smoked-salmon starter is £22.
