I want a restaurant in the north of Cambridge that is within a moderate price range.
There are two restaurants fitting your description, one is Chinese cuisine and one is Indian cuisine. Do you have a preference?
Please book a table for 4 at the Chinese place at 12:30 on Sunday and give me the reference number.
Okay you're all set for Sunday at 12:30. Your reference number is F5BTP63A. Can I help you find anything else?
