Hello! Could you share what motivated you to start in the luxury dining sector, and how have your early experiences shaped your current vision of the industry? 

From an early age, I was captivated by the artistry and discipline of fine dining. My family-owned restaurants in Lyon, including a two Michelin-starred establishment. My grandfather, a well-known chef, was a huge influence and remains a constant source of inspiration in my life. Studying at the Ecole Hôtelière de Lausanne deepened my appreciation for excellence and the finer details of hospitality. But it was my time working alongside Chef Gordon Ramsay, particularly at The Claridge’s Hotel in London, that truly opened my eyes to the power of precision and passion for delivering excellence day in and day out.Those formative years shaped not only my standards, but also my core belief: luxury is about more than just what is on the plate. It’s a theatre of experiences. We often tell the team, we’re no longer in the hospitality business, we’re in the entertainment business. 

Throughout your career, you’ve led numerous restaurants. In your opinion, what are the key steps to successfully opening a luxury restaurant? 

It all starts with a clear vision as you need to know exactly what story you're telling. Luxury lives in the balance between consistency and surprise: meeting expectations while delivering the unexpected. 

Then it’s about building the right team; people make the place. From there, every detail matters: the design, the service flow, the menu, the lighting, even the scent. At Thesleff Group, before launching any new concept, we conduct thorough internal trials. We invite our team to experience the full offering firsthand. This hands-on approach allows us to refine every element including food, beverage, and service before any guest walks through the door. The result is an experience that feels seamless, deliberate, and unforgettable. 

As Chief Operating Officer of the Thesleff Group, you manage a diverse portfolio of restaurants. How do you balance culinary excellence with luxury? 

For me, the two go hand in hand. Culinary excellence is the foundation, but luxury is the emotional connection. It’s how a guest feels from the moment they walk in, to the moment they leave. At Thesleff Group, we focus on creating experiences that are both aspirational and deeply personal. Luxury, to me, is about anticipating your guest’s needs and recognising them before the guest even realises them. That’s where true excellence lies. 

You’ve played a key role in achieving prestigious accolades such as "Restaurant of the Year" and nominations in the "World’s 50 Best Bars". What role does innovation play in the success of your establishments? 

 

Innovation is vital. The moment you stand still, the industry moves past you. Whether it’s the menu, the design, the guest journey, or technology, we’re always searching for new ways to engage and excite. But innovation must feel seamless, never forced. 

By closely listening to our guests and staying ahead of global hospitality trends, we continuously refine our offerings to exceed expectations. You see this in action at Los Mochis London City, where our TENrei Tuna Ceremony offers an immersive culinary experience. It deepens guests’ appreciation of Japanese cuisine by showcasing the grace and precision involved in the preparation of Bluefin tuna. 

At Viajante87, now featured on the World’s 50 Best Bars list, we launched the Culture Exchange series in 2024. Each month, we welcome some of Latin America’s most celebrated chefs and bartenders to London, creating a vibrant, authentic cultural and gastronomic experience for our guests. 

Luxury in dining goes far beyond the quality of food. In your view, what are the essential elements that define a luxury dining experience? 

It’s about detail, discretion, and a sense of occasion. Luxury is feeling seen without being watched, pampered, but never in a performative way. From the tone of voice your waiter uses, to the quiet elegance of how your coat is returned, it’s all about those invisible touches that define the experience. 

With your extensive experience, what advice would you give to someone aspiring to succeed in the demanding world of luxury dining? 

Be humble, be curious, and never stop learning. Listen more than you speak. This business is about people. People should always be at the centre stage of any luxury organisation. Guests, of course, but just as importantly, the team who brings the vision to life every day.
