U: I would like to visit a college while in cambridge.

S: We have 18 colleges in Cambridge! Is there a certain area you had in mind? If not, I recommend Churchill College in the west.

U: I was really hoping for something in the centre of town.

S: There are 13 colleges in the centre. Would you like me to recommend one?

U: Yes that would be great!

S: Christ's college is particularly nice. It's located on Saint Andrew's street and the entrance is free. Does that sound good?

U: Yes, thats great. Can you give me their postcode please?

S: Their postcode is cb23bu. Can I help you find anything else today?

U: Yes, I also need to book the aylesbray lodge guest house. Starting Saturday. 3 nights, 5 people. Please inclue a reference number.

S: Booked! Your reference number is: EKFWZC8W.

U: Can you make certain I get a room that has strong water pressure in the shower?
