This is our second time visiting Budapest. We knew there were two Michelin one star restaurant in Budapest and Onyx is one of them. We made a reservation before we arrived in Budapest and got confirmation by e-mail. The restaurant also called me a few hours before dinner to confirm. Overall, our experience there was quite positive. We had the tasting menu and each dish was well prepared, although the foie gras was a bit too much. My girlfriend got quite full after that dish.
We went on a Saturday so it was quite occupied. The service was very good. But we could feel the difference comparing to Costes.
