Gastronomy
The ONYX²⁸ menu is built on seasonality, premium ingredients, and precise technique. Each plate is carefully orchestrated — textures, temperatures, and contrasts create a layered experience that unfolds bite by bite. The focus is on elegance in presentation and depth of flavor. Nothing is superfluous. Everything has a purpose. In our expression, bistronomy means high-end gastronomy without rigidity — luxury that breathes.
Philosophy
Our philosophy is rooted in top-tier French bistronomy — a concept that blurs the line between haute cuisine and relaxed elegance. Under the leadership of Chef Mario Mandarić, ONYX²⁸ develops a distinctive signature that celebrates technique, structure, and depth of flavor. Each dish is conceived as a composition: balanced, aesthetically refined, and executed with near-architectural precision.
Fine dining, for us, is not a form — it is an emotion.
It is an experience that transcends expectations.
Experience
Sunset over the sea, the lights of the town of Hvar in the distance, and the fortress watching over the evening create an unforgettable setting. The ONYX²⁸ rooftop terrace becomes a stage where gastronomy, architecture, and emotion come together. Every evening is carefully curated. Every detail thoughtfully considered. Every moment worth remembering.
RESERVATIONS
We do not rely on local or regional tradition. Our identity is international, contemporary, and self-assured. Inspiration is drawn from the French culinary school, while the interpretation is bold, modern, and global.
