We had heard some very good stories about this restaurant but were quite disappointed. We had a 3 course menu, which tasted good, nut the quantity was way below par. No one asked whether we actually liked the food ... so we had to make our complaints ourselves. This I find very awkward for a restaurants that's supposed to be "top". Btw nothing was actually done with our complaints until we spoke to the owner (?) when paying; "Oh but we could have given you some more of that delicious meat" ... Disappointing!
Also some of the electric lights were off due to electricity failure (beyond the control of Zarzo). Our table was very dark and we could hardly see the food ... which was seen as an unpleasant coincedence for us by Zarzo ... For me it is unacceptable to discharge these things so easily if you pretend to be a top restaurant and you charge these prices.
My suggestion: go to Wiesen!
