Aux pains de papy is a small bakery on Gray's Inn Road in King's Cross that sells croissants and coffee. Its main items are almond croissants, cinnamon buns, and pistachio pain au chocolat. The croissants have a crust that shatters like dry leaves, with a buttery, chewy crumb inside. The bread is best eaten the day it is bought, and the shop is closed on Sundays.
