I would like to find some entertainment in the centre of the city.
I don't have anything that meets those criteria. Can I check something else for you?
How about some architecture to visit in the center?
I am showing 5 architecture in the centre. I could recommend all saints church.
Ok, what's the phone number?
They are reachable at 01223452587, anything else that I can assist with?
Yes, please find a restaurant in the moderate price range and same area as the attraction.  
I am showing 21 restaurants in that area and price. Is there a certain cuisine you would enjoy?
How about portuguese food? 
Unfortunately, there are no portuguese restaurants that meet your requirements. Can I look for something else for you? 
How about international food?
I am showing two international restaurants near the centre. The Varsity Restaurant and Bloomsbury Restaurant. Would you like more information on either one?
Please book the Varsity for 5 people on tuesday at 17:00. 
Sure, your booking was successful. The table will be reserved for 15 minutes, reference number E8SV1E0D. May I assist you with anything else? 
That is all thanks.
You're welcome. Have a nice day.
