Sunday, May 10, 2026 — a one-day ONYX study trip heads to the Swabian Hill (Svábhegy) Observatory for a stargazing showcase paired with a three-course tasting. The experience channels the 1960s Space Race through the restaurant’s own story, blending celestial sights with culinary craft in the hills of Budapest.
What’s on the menu
After the observatory visit, guests choose between two paths. Option one: a shorter restaurant visit built around two iconic dishes, a quick bite that still hits ONYX’s greatest-hits notes. Option two: a seated, six-course lunch that dives deep into the ONYX universe, a full tasting menu designed to chart a course from liftoff to lunar landing on the plate.
Atmosphere and arc
The day is curated to feel like a time capsule: mid-century ambition, telescopes pointed skyward, and plates that riff on innovation and precision. It’s a culinary-cosmic crossover where the observatory session sets the scene and ONYX’s kitchen writes the epilogue. Cover image: ONYX Budapest.
