The story

National da Sergio | Elevated Franco-Italian Dining in Olten, Switzerland

At National da Sergio, Olten’s Klosterplatz becomes a stage for refined Franco-Italian cuisine that Sergio Salsi and his brother-in-law, head chef Ivano Boschi, have been perfecting for years. “Italienisch für Fortgeschrittene” – Italian for advanced palates – is the motto here, and it suits a kitchen that treats classic French and Italian cuisine not as a simple repertoire but as a living craft.

The dining room is gemütlich, warm and welcoming, where Sergio Salsi tends to guests with genuine care while Ivano Boschi works the stove. The menu shines with handmade pasta, intricate meat preparations and well-judged fish dishes – all rooted in the traditions of both countries. A carefully curated wine cellar supports every course with excellent pairings.

This quietly confident approach earned National da Sergio a Michelin recommendation, acknowledging that quality here is no accident – it is the daily standard. The kitchen’s consistency and the owners’ personal touch make the restaurant a fixture for those who value substance over fanfare.

Whether for a business lunch or a leisurely dinner, National da Sergio delivers the kind of Franco-Italian cooking that feels both timeless and alive – sophisticated, grounded, and genuinely satisfying.
