U: Hello, I'm looking for a college to go to.

S: I can certainly help with that. We have 18 colleges around the city. Is there a certain area you prefer to visit?

U: What's the most popular? May I have the postcode, entrance fee, and what area is it in?

S: Christ's college is popular.  It is in the centre and does not have an entrance fee.

U: Yes, thank you that will be fine.

S: Christ's college is located at saint andrew's street in the centre and their postcode is cb23bu.

U: Wonderful. I am also looking for a moderately priced place to stay with a 4 star rating. I would like for it to have free wifi and in the west.

S: There are no establishments matching your criteria. Would you like to try another part of the city?

U: Can you then search for one that is in the South?

S: Yes.  I would recommend Aylesbray Lodge Guest House in the south.

U: Does the hotel have good water pressure?
S: The rooms at the Aylesbray Lodge Guest House suffer from low water pressure issues. Want to look somewhere else?
