Yes, I'm looking for a restaurant in the centre what serves world food.
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?
I would like a gastropub then if you have one open.
I would suggest The Cow Pizza Kitchen and Bar.  Great food.  It is located on Corn Exchange Street.
What is the price range?
It is moderately priced. Would you like me to make a reservation?
no, just give me the address
Sure, the address is on Corn Exchange Street, post code cb23qf. Can I do anything else for you today?
I do need to get from Stevenage to Cambridge on Saturday. I'd like to leave shortly after 09:45, if possible.
TR9024 leaves at 09:54, would that one work?
Yes, that would work out great.  I need to book the trip for four people.  Can I get a reference number too please?
Reference number is : 1QXKJN3D. Is there anything else?
No, that's all I need right now. Thank you so much.
You're welcome, have a great day and goodbye!
