user: Yes, I'm looking for a restaurant in the centre what serves world food.

assistant: I'm sorry, but there are no foods in the centre that serve World Food. Would you like to try another area or a different type of food?

user: I would like a gastropub then if you have one open.

assistant: I would suggest The Cow Pizza Kitchen and Bar. Great food. It is located on Corn Exchange Street.

assistant: It is moderately priced. Would you like me to make a reservation?

user: no, just give me the address

assistant: Sure, the address is on Corn Exchange Street, post code cb23qf. Can I do anything else for you today?
