Les Clefs d'Argent sur Mont-De-Marsan

Yes, but... This review, which is entirely my own, concerns a high-end establishment, or rather, an establishment that charges high prices, hence my reservations. I'm posting it for those who are lucky enough to have friends who will treat them to a 6-course tasting menu (without drinks) for a hefty 90 euros per person. We couldn't go whenever we wanted, but oh well... we went anyway. The weather was beautiful and warm, and we were in the (rather ordinary) outdoor courtyard of the restaurant with three other couples. Upon arrival, we were offered water—still or sparkling—so we ordered still water (which cost us 7 euros at the end of the meal). Then they brought us the wine list, or rather, the wine bible. I must say, we were a little taken aback by the almost endless selection of wines and their prices (about three to five times the price of a bottle). Anyway, we had a very ordinary 8-euro kir as an aperitif. Since we didn't want to pay between 8 and 18 euros for a glass of wine or 60 euros for an ordinary bottle, we ordered a 26-euro bottle from a well-known winemaker in Gascony whose wine sells for 7 euros in supermarkets. The dishes on the menu were beautifully presented and quite good, even very good (that's 15 euros each, though), but that's undeniable—it's the work of a chef. What really bothered us was that, with such a high-priced menu, we weren't offered an aperitif and wine pairings upfront. Quite frankly, the food was good, but it lacked that extra something, and I think the wine pairing was largely to blame, as was the disproportion between what should have been a memorable experience and the price.

Still as good as ever! We discovered this restaurant when we lived in Mont-de-Marsan about fifteen years ago, and it's always a pleasure to go back during our holidays! Excellent market menu today with a delicious dessert. Thank you!

A refined place with delicious cuisine and exceptional service

Yet another exceptional experience offering a diverse range of culinary delights! The only downside was the background music, which wasn't quite right for the setting.

We were delighted with this refined experience, thanks to the natural and elegant setting, the impeccable service, and the excellent cuisine. Thank you for this haven of well-being.

My numerous reviews allow me to award this restaurant a "Perfection" rating. Culinary art brought to life in perfect harmony, a wonderful experience, accompanied by service that was both very friendly and discreet. As a lover of sweets, I was, after so many other culinary delights, completely captivated by the two desserts. The wine list is a veritable encyclopedia. You do our city proud. SUPLIME

An exquisite romantic lunch! The Chef delighted us once again, particularly by showcasing the asparagus so beautifully this time of year. Every dish lived up to our expectations, including the wine. The staff was incredibly attentive. A huge thank you for this enchanting culinary experience.

The best restaurant in Mons! (By far…) Kindness, excellence, audacity, passion, emotion… and love! At every moment, the magic happens… ✨ January 16, 2026, forever etched in my memory and in my heart… What incredible luck! 🍀 Thank you for this truffle-filled menu and this evening! It was simply amazing!

A delightful moment both in terms of taste and relationships.

Christophe and Eugénie transport us to an enchanting world of flavors and discoveries, all delivered with great professionalism and contagious good humor. Highly recommended.
