From a 32-seat bistro to a 3,000 m² hospitality landmark, L’Amusoir marks half a century of family passion in Waterloo
In December 2025, L’Amusoir in Waterloo celebrates an extraordinary milestone: 50 years of continuous family-run hospitality. What began as a modest bistro in 1975 has grown into one of Belgium’s most recognisable restaurant destinations. Today, it stands as a symbol of consistency, warmth, and entrepreneurial vision.
Moreover, L’Amusoir’s story mirrors the evolution of Waterloo itself, from a quiet town to a vibrant culinary hub.
From a Small Bistro to a Bold Beginning
The story starts with Thierry Blanchart, just 22 years old at the time. In 1975, he discovered a small 70 m² farmhouse in Waterloo. The building could seat only 32 guests. Still, he saw potential where others saw limits.
With little money but enormous determination, Thierry renovated the space with friends. He opened L’Amusoir on 27 December 1975, his birthday. Thanks to a last-minute loan from the local postman, the doors finally opened.
That spirit of solidarity would shape the business for decades. 
When Food Took Centre Stage
At first, L’Amusoir served drinks and sandwiches. However, customer demand quickly changed everything. Thierry introduced simple dishes, then pasta, and eventually full meals.
One dish became legendary: the giant gratinated spaghetti. It turned L’Amusoir into a local favourite almost overnight.
As a result, the venue evolved naturally, guided by guests rather than trends.
A Defining Partnership
Four years later, Thierry met Françoise, a customer who soon became his partner in life and business. Together, they expanded their vision. In 1981, they purchased the neighbouring building. There, they opened Les Demoiselles des Mers, a seafood restaurant led by Françoise. Later, other concepts followed, including Menu Folie and what is now the Chalet de l’Amusoir, famous for its fondues.
Step by step, a hospitality ecosystem was born.
Expansion Without Losing the Soul
As demand grew, so did the space. A rear terrace appeared. Then came a pond. Later, an event venue called Le Couloir opened for private and corporate functions. 
Despite its growth, L’Amusoir never lost its identity. Each new space kept its own personality. Importantly, nothing was copied or mass-produced.
That philosophy still defines the brand today.
Passing the Torch to the Next Generation
When Thierry fell seriously ill, the future arrived sooner than expected. His sons Jérôme and Jonathan stepped in.
They learned every role. They worked in the kitchen, the dining room, and even the garden. Eventually, Jérôme took over Le Stamp, while Jonathan assumed leadership of L’Amusoir and later the Bar de l’Amusoir.
Today, the second generation runs the group with confidence and respect for its roots.
Why L’Amusoir Still Succeeds
Many ask why L’Amusoir has lasted so long. The answer is simple.
First, it offers consistency. Second, it delivers strong value for money. Finally, it adapts quietly to changing habits without chasing fashion.
As Jonathan explains, this is a place built with heart. Jérôme adds that every venue has its own identity, team, and menu. Guests feel that difference.
A Group That Grew from One Address
L’Amusoir became the foundation of what is now the Art Blanc Group. The family business owns 12 establishments in Belgium, as well as a Relais & Châteaux hotel in Mauritius.
Despite this scale, the group remains 100% family-owned. Decisions stay human. Values remain unchanged.
Twelve Months of Celebration
From 27 December 2025 to 27 December 2026, L’Amusoir will celebrate its anniversary year.
Highlights include:
- A reunion dinner with former team members
- A six-hands menu by historic chefs
- A commemorative book retracing 50 years
- Signature dishes returning to the menu
- Renovated interiors featuring archive photography
The celebration honours both past and future.
More Than a Restaurant
L’Amusoir is not just a restaurant. It is a meeting place. A landmark. A second home for generations of guests.
For Waterloo, it represents continuity and trust. For Belgian hospitality, it proves that family values still matter.
After 50 years, L’Amusoir continues to welcome guests the same way it always has — like friends.
