Are their any architecture in the centre of cambridge?
Yes! There are 4 churches as well as old schools. Would you be interested in one of those? 
Certainly, pick out a good option. I will need the entrance fee please. 
I would like to suggest all saints church. The entrance fee is free. 
Excellent, could I also get its postcode and phone number?

Could you give a recommendation on a place to eat in the centre that is in a moderate price range?
The Copper Kettle is an excellent choice for British cuisine. Alternatively, there is also an asian oriental restaurant. Do either of those sound suitable?
I'll go with The Copper Kettle. Can you give me the phone number?
