I'm looking for a good place for entertainment in the centre. Any recommendations?
Unfortunately there are no places in the centre. Would you like to try another area?
Lets drop entertainment and look up one for the type of college.
There are 13 colleges in the centre. Do you have one in mind?
Any one would be fine, can I just get the address, phone number and postcode?
Christ's college, in the centre of town. Number is 01223334900. Address is post code, cb23bu, Saint Andrew's street. No fee to enter. Do you need anything else?
