"Butter is at the heart of a croissant. Aux Pains de Papy founder Mathieu Esposito knows this, and the croissants at this très Français bakery on Grays Inn Road are the most faithful to France’s high bottom level for pastry and consequently one of the best in London. Honeycomb layers, a properly burnished exterior, and butter, so much butter. Best enjoyed warm on a mad dash down the road, with pains aux chocolats, croissants amandes, and a noble Paris Brest also worth a look." - James Hansen
