Robin Birley opened Oswald's on Albemarle Street in 2018, out of a wish for old vintages at fairer prices, and named it after his grandfather, the portrait painter Sir Oswald Birley. It is a dining club: the wine list is priced at or below what a shop would ask, members bring their own bottles without corkage, and each can keep up to twelve in the cellar.
It is also the hardest door on this list. There is no form, nothing published and no social media.
