I'm very surprised when I saw VaKwiththemizz's comments and I believe that must be some misunderstanding. I'm from Shanghai China and I can prove Chinese are welcome in Zara's Restaurant.
I visited Zara's once and I was impressed by the food and service so I decided to arrange a surprise for my friend(she is Chinese too) when she was visiting Amsterdam in March. I communicated with Susie the manager of restaurant via emails because I was not able to visit Amsterdam with my friend. Susie and her colleagues made a great arrangement beyond my expectation for my friend's birthday celebration. There were the balloons and flowers and awsome food. All the employees of Zara's came to say happy birthday to my friend. They gave a girl and her friend a wonderful night!
I wouldn't deny that I'm a big fan of Zara's and I will recommend Zara's to my friends in China to have a nice meal here when they visit Amsterdam.
Zara's is not some kind of luxurious restaurant but it's more like the home to the guest.
