The restaurant is located in the historic district of the city center. It is classified as a UNESCO historic monument because it houses unique frescoes dating back to 1794. This is the work of Brother Abraham, a monk from the Abbey of Orval. “Onesto” dates back to 1979 and was previously called Georgio. Today, the establishment welcomes many regulars as well as tourists and businessmen.

Beyond this exceptional frescoed hall, the restaurant features a magnificent terrace with seating for about thirty people and a veranda with space for about twenty. Groups can benefit from separate spaces. Onesto is known for its wood-fired pizzas, pasta, bread, and homemade tiramisu.
