Could the closure of a Michelin-starred restaurant actually lead to something positive? That’s exactly what’s happening in Tremblay-sur-Maulder, in the heart of the Yvelines (78). There, L'Auberge Nouvelle opened its doors this February 2026, at the very address of the former Numéro 3. Laurent and Julie Trochain managed this acclaimed gastronomic spot for twenty years before deciding to move on. It’s a bittersweet moment for loyal patrons, but the new chapter promises plenty of delightful culinary surprises.
The once intimate, upscale dining atmosphere has been replaced by a spacious, friendly, and welcoming setting. The concept is bold: everything has been completely rethought to establish a fresh new vibe. The decor is simplified, tables are expanded to seat up to 80 guests without feeling crowded, and reservations are no longer necessary. This is a welcome change from before, making the experience all the more enjoyable. At the heart of the space, two moving cheese bars operate like sushi counters, immediately catching the eye. Walls are brightened up with artwork from renowned artists, creating a relaxed brasserie atmosphere far removed from typical fine dining standards. It’s more convivial, and honestly, we’re not complaining one bit.
In the kitchen, the message is clear and unequivocal: "We gave it our all for 20 years, but it's over." The new goal is to serve well-executed classic dishes, crafted from seasonal ingredients and sourced from local producers. The menu at Auberge Nouvelle celebrates the rich flavors of the Île-de-France and Yvelines regions: organic eggs from La Ferme du Loup Blanc, trout from Villette Fish Farm in Rosay, snails from Maison Devaux in Favrieux, duck from La Ferme du Loup Ravissant in Bazainville, ravioli from Maison Mathy, and black pudding from Maison Parra... The list of dedicated artisans involved is long and genuine—a true network of passionate craftsmen supporting the establishment.
We sampled several dishes from the menu and are sharing our initial impressions. The organic egg with homemade mayonnaise is straightforward and comforting, just as it should be. The housemade country terrine is sure to please traditionalists. But our top favorite by far goes to the snails from Devaux house, in garlic and parsley butter: tender, perfectly seasoned, absolutely delicious.
On the entrée side, the classic veal blanquette offers a comforting, traditional touch, while the sautéed black pudding slice pleasantly surprises with its hearty texture reminiscent of a generous, flavorful shredded meat, complemented by a perfectly balanced apple compote. We wholeheartedly recommend trying both.
Probably the hallmark of L'Auberge Nouvelle is its cheese bar at the counter, available on Friday evenings and during weekend lunches and dinners. In collaboration with Les Fromages de Clément in La Queue-les-Yvelines and Tout un Fromage in Rambouillet, the bar features a rotating selection of cheeses, each served with fresh or candied fruits. The plates are color-coded (yellow at €6.50, pink at €8.50, green at €10.50), and guests help themselves at their own pace within a 1.5-hour window in the evening. Bread is available as much as you want. A simple yet effective concept, infused with a spirit of sharing that we genuinely appreciate.
Finally, we couldn’t resist the decadent crackle chou profiterole-style, filled with vanilla ice cream and served with warm chocolate sauce—rich, well-made, and truly satisfying. We also enjoyed the Pear Belle Hélène with its perfectly poached pear, hot chocolate sauce, and generous whipped cream: a timeless classic given a thoughtful refresh, proving that great recipes don’t need to be reinvented to impress.
Great news: l'Auberge Nouvelle is kicking off its musical evenings this Sunday, March 22, 2026, with a performance by the band Minuit Bleu. This inaugural event is likely just the beginning. Dining and enjoying live music in one place, outside of Paris, offers a refreshing change. Keep an eye on l'Instagram of l'Auberge Nouvelle to catch all upcoming dates. The welcome is friendly, and the atmosphere is wonderfully down-to-earth: open to everyone, no fuss, embodying the genuine spirit of traditional inns from days gone by.
On the practical side, the "Auberge 1996" menu at €19.96 (served lunchtime from Monday to Friday) makes the house very accessible. Children are now warmly welcomed with a specially designed menu at €15—a significant upgrade from the previous fine dining experience. When summer comes, an inviting terrace will offer outdoor dining, reminiscent of a private garden. To make a reservation or view the menu, visit Auberge Nouvell’s website or call 01 34 87 80 96. The restaurant is located at 3, Rue du Général de Gaulle, 78490 Tremblay-sur-Mauldre, open for lunch from Monday to Sunday between 12 pm and 2 pm, and for dinner from Friday to Sunday, 7 pm to 10 pm.
Laurent and Julie Trochain had previously announced their plans to unveil a gallery, and that goal is still on track. Visitors can now tour the space and purchase artworks by appointment in one of the adjacent rooms on the premises.
Our opinion: With a menu priced under 20 euros and a selection rooted in local Yvelines products, Auberge Nouvelle offers a genuine answer for those craving good, affordable food. Some might find it slightly pricey, but remember, this is homemade cuisine made with regional ingredients—it’s all about comparing similar standards. Nostalgic for the innovative dishes of Le Numéro 3 and seeking refined cuisine? You’ll need to look elsewhere. But if you’re after a hearty, homemade meal in a friendly setting, this place ticks all the boxes. It’s perfect for family dinners, romantic evenings, or gatherings with friends—whether you want a glass of wine with cheese boards or a full meal. As purchasing power declines, there’s a nostalgic return to simple, sincere dining experiences, and Auberge Nouvelle arrives just at the right moment.
Who is it for: food enthusiasts of local specialties, families, curious visitors eager to explore the best offerings from Yvelines farmers, and anyone looking for a quality, accessible dining experience away from the hustle and bustle of Paris in the Yvelines region.
