Very friendly staff if sometimes a little inexperienced. Good atmosphere and prompt service. Our waiter happily fetched a colleague to explain some of the options to us in English - no complaints, we don't speak Hungarian.
Pleasant, fresh decor, bistro like. Menu had lots of tempting choices and we were all very happy with our own dishes. All were beautifully and imaginatively presented and the quality was excellent. Deserts were attractive and more-ish. We had a very good bottle of Hungarian wine and they were happy to provide tap water.
We left hoping to book for the next night but were disappointed to find they closed on Sundays and Mondays. If staying at the Palazzo Zichy this is so convenient, you literally have a dozen steps from the front door, you don't need to wrap up!
This was by far the best meal we had in Budapest.
They take credit cards and don't add a tip.
