Eleven courses. Sixteen seats. A communal table that carries you from the 1700s to the year 3000 — Budapest fine dining as an act of collective imagination.
Onyx occupies a specific place in the history of Central European fine dining: it was the region's first two-Michelin-starred restaurant, a distinction that shaped the city's culinary ambitions for a decade. In 2025, the restaurant returned in a radically different form. The ÆTHER concept — sixteen seats at a single communal table, an eleven-course menu that moves through two distinctly designed spaces — is unlike anything else in Budapest.
The premise is temporal. The menu traces a culinary arc from the 1700s toward the year 3000, each course corresponding to a different era of food culture. The first space anchors guests in history — classical techniques, heritage grains, preparations that reference Austro-Hungarian culinary tradition. The second space is a vision of the future: fermented, preserved, compressed, and grown. Between them, the present: Hungarian produce at its purest.
The ÆTHER experience runs Thursday to Sunday, with all guests arriving at the same time and moving through the evening together. From Monday to Wednesday, the adjoining Műhely workshop operates an à la carte format called Mozaik, where the same kitchen applies its considerable technique to a more accessible menu of individual dishes. Both formats share a location of unimpeachable significance: Vörösmarty tér, at the heart of Budapest's historic inner city, steps from Café Gerbeaud and the Danube promenade.
The ÆTHER format is designed for impressing clients who have eaten well and thought they had seen everything. The communal structure also makes it extraordinary for team dinners where you want to create a shared memory rather than just a meal. The Thursday-to-Sunday full experience demands a special occasion; the Monday-to-Wednesday Mozaik à la carte is a perfect choice for closing a deal — exceptional food, individual tables, a setting that signals serious intent.
