There are not. There are a number of Chinese restaurants in the city centre from cheap to expensive. Do you have a price range?
Are there any restaurants that serve New Zealand food? OK, can you find any Chinese restaurants in the town centre? I don't care about price. I need to book a table for 4 at 18:45 on Saturday.

I'm afraid none of the restaurants are available at that date an time. Is there another date or time that would work for you?
