During my 5 months stay in the city, I went to Köleves at least 4 times.
The last time was the first time I went to their new restaurant. Seems to me that the food used to be much better before they moved. Now it was over-spiced and too creamy. I hope they'll get their old standards back soon!
Also the atmosphere in their old rooms was much nicer. Simply more homey and comfortable. Now it's kinda old (ok, it's winter) and echo-y.
