I been there one week ago, it was a monday and the restaurant was full, luckily i placed a reservation in advance. I tried other time to go and eat there but it was always fully booked and without any guest list (strange). The person with i spoken sounds a bit in rush.
They gave us a tasty amuse bouche and tasty bread, well done.
I had the Carpaccio as started and my fiancée got the soup. Both tasty but the presentation of the carpaccio was a bit messy and not easy to eat mixing all the ingredients. Then followed bymain course, lamb and fish, both well done. The ambient is really too small and noisy, and it was just a monday, when you want go to toilet be careful to the other tables cause it's really narrow. The girl that pour for me the wine dont' know how to do cause she lean the neck of the bottle to my glass edge. Small particular that makes a usual place in something outstanding. Zazas got the potential to separate itself from the rest of soulless Amsterdam restaurant, just a bit more of effort and more of customers care to be a nice reality of Amsterdam.
