When chef Pierre Manceron presents his aristocratic employer and his guests a completely new kind of dish, he is fired on the spot. According to nobility, food is not supposed to be messed around with. Manceron and his son flee to the country and start a tavern there. That works, but not with enthusiasm. But a mysterious guest called Louise finds a way to let Manceron find his pleasure in cooking again. It does not take long for them to turn the simple tavern into a gastronomic paradise: the first French restaurant! And while the French aristocracy keeps holding on to the past and the dishes they are familiar with, Délicieux shows us how the revolution is about to begin and in a surprising way starts in the kitchen.
