Hassan Kadam (Manish Dayal), the oldest of five siblings, was taught how to cook, but more importantly truly taste and love food, by his mother. Their entire family works together in their open air eatery in Mumbai. In his role, Hassan considers himself a cook and not a chef as he was never professionally trained. Following the tragic death of Hassan's mother, his well-off but frugal Papa Kadam (Om Puri) decides to pack up the family and move to Europe to open a restaurant, the business to keep to his wife's memory in their love of South Asian cuisine. After an initial business misstep in London, Papa believes it is fate that their van breaks down just outside of the French town of Saint-Antonin-Noble-Val, that they meet a local foodie, a young woman named Marguerite (Charlotte Le Bon), who introduces them to the abundance of fresh locally sourced produce, seafood and meats, and that there is an abandoned restaurant property on the outskirts of town for sale. Against the wishes of the family, Papa decides to purchase the property for their business, even after learning that the previous owners could not make a go of it because it is a mere one hundred feet from Le Saule Pleureur, a Michelin-starred restaurant where Marguerite works as a sous-chef, she trying to work her way up to chef-de-cuisine. Papa's resolve is strengthened as he believes their style of food is not only different than the French, but better in their bold flavors, something he wants to show the locals. Madame Mallory (Dame Helen Mirren), Le Saule Pleureur's proprietress, took over its running following the death of her husband. The restaurant is now her entire life, and she has waited close to thirty years for it to receive its second Michelin-star, so far without success. Madame Mallory does not take too kindly to her new neighbors, not only as potential competition, but in the Kadams', most specifically Papa's, brash and forward approach to life, unlike the refined French. An initial action by Madame Mallory to make sure Maison Mumbai, the Kadams' restaurant, doesn't succeed, leads to an all out war between her and Papa. But a potential bridge emerges between the two restaurants with the budding friendship and possible romance between Hassan and Marguerite. Beyond that friendship and romance, Hassan believes, to survive, they have to meld their bold flavors to local ingredients and techniques, he who wants to learn the art of French cooking from Marguerite. A singular action in that war results in what could be a fundamental shift between all the players at Le Saule Pleureur and Maison Mumbai.
