In the heart of Charmes-sur-le-Rhône, along the main street, it's easy to miss, as the entrance to the beautiful blond stone building is on the side, and there's no eye-catching sign.
It was while cycling in the area that Olivier and Stéphanie Samin fell under the spell of an establishment that had been closed for several years.
It was here that Olivier Samin decided to open his own restaurant, having completed his culinary training as head chef at the famous Maison Pic in Valence. As for his wife, Stéphanie, a nurse, she completely changed careers, managing the hotel side of the Carré d'Alethius.

Nothing predestined Olivier Samin, originally from the Creuse region, for a career in gastronomy. Except perhaps his grandfather, a passionate cook who took young Olivier under his wing. "He was a bit like my first mentor," Olivier recalls. "You had to be disciplined! I completed a four-year vocational baccalaureate at the hotel school in Clermont-Ferrand, specializing in catering and hospitality. I didn't really have a clear idea of what I wanted to do, except that it had to be hands-on, physical. My teachers all saw me working in the dining room, but I was far too shy and preferred to be in the kitchen."
A character trait that will never leave him is already emerging: a certain reserve, far from the media figures of gastronomy, but a demanding nature that is fully expressed behind the stoves.

Despite his formal training, he admits he didn't really know what gastronomy was. Then everything fell into place. At the end of his final internship at Le Vieux Castillon, Olivier Samin was immediately hired. The young chef then discovered the world of Michelin-starred cuisine and gained a wealth of formative experience. In the Basque Country, at Firmin Arrambide's restaurant, he immersed himself in other terroirs and other products. But it was in Burgundy, working with Jean-Michel Lorain, that he had a real epiphany. It was this experience that introduced him to the very highest level... "An incredibly demanding environment. Caviar, turbot... What a thrill to see those huge tins of caviar for the first time!" He was part of the team when Jean-Michel Lorain earned his third Michelin star in 2003.
It was in Burgundy that Olivier Samin met Stéphanie. The couple decided to move to a different region, settling in the Drôme where Olivier joined Maison Pic in Valence. In seven years, he climbed the ranks, from chef de partie to second-in-command to Anne-Sophie Pic when she earned her third Michelin star.
From Provence to the Basque Country, from Burgundy to the Rhône Valley, Olivier Samin honed his skills alongside demanding chefs who instilled in him far more than just technique: a respect for the ingredients, a taste for precision, and a constant pursuit of excellence. He feels ready to open his own restaurant. Because beyond the technical mastery acquired from the greatest chefs, Olivier Samin feels the need to tell his own story on the plate. A more personal cuisine, guided by emotion, the ingredients, and instinct rather than by mere showmanship.

The beginnings weren't necessarily easy; the approach was no longer the same. "There were only two or three of us in the kitchen, now our staff has doubled. We didn't really know what to do, we were searching... Then our cuisine became more refined, more distinctive in our way of working and plating the dishes. I only want to highlight two or three flavors in a dish, to go into even more detail."
As for his recipes, Olivier Samin sets no limits, imposes no constraints on himself. No signature dishes, no fixed recipes. "There are no rules," he says. "Some dishes come to me naturally, as if by instinct, while others never come to fruition. We are fortunate to live in a region, at the crossroads of the Ardèche, the Drôme, and Provence, which is rich in beautiful produce. These are my true source of inspiration: fruits and vegetables, Eyrieux snails, local cheeses and wines, chestnuts, Ardèche truffles… As the seasons change, I elevate them through instinctive cooking."
Inspired by the seasons, creations emerge where just three or four flavors converse in subtle harmony. It's a cuisine of restraint rather than ostentation, favoring emotion over complexity.

On the plate, this philosophy translates into a refined and straightforward cuisine. Olivier Samin doesn't seek to multiply effects or artifice. Each ingredient retains its identity, each flavor finds its place. Precise cooking, measured seasoning, and delicately crafted textures combine to create dishes where balance takes precedence over showmanship.
Olivier Samin works closely with local producers who share his dynamism and love of the product.
Olivier Samin has kept his star since 2014. Want a second one? Without it being his objective, this quest for a second star allows him to further develop his cuisine, to satisfy his compelling desire to always go further.

Maintaining the consistent quality of fine dining is demanding, both in terms of work and time. Why did you choose to offer overnight stays and special packages? "Quite simply because it ensures a certain level of business, guaranteeing us a more regular clientele. And guests appreciate being able to enjoy a gourmet dinner with wines without having to worry about getting home. We also have vacationers who stay for a few days, but we don't offer half-board; we are a fine-dining restaurant. And to relieve stress, I do sports, running, cycling… Out in nature, I'm alone; it's peaceful."
One last question: do friends dare to invite a star chef? "It is true that at the beginning it was only my mother-in-law, who prepared a very good pot-au-feu, by the way," smiles Olivier Samin.
Like his restaurant, which one discovers almost by chance at a bend in the road in Charmes-sur-Rhône, Olivier Samin does not seek the limelight. He prefers to let it shine on his plates.
