Hi! I need to find a train to Ely. Can you find me one that doesn't leave until at least 17:30?
Yes, what day are you traveling?
I need to leave Cambridge on Tuesday.
We have 4 trains that fit that. Any specifics on arrival or departure times?

Thank you. I am also looking for places to go in town. Are there any architecture sights in the city centre?
Yes, I can recommend up to five different architecture attractions in the Centre area.  How about All Saints Church?
That sounds wonderful. Can you give me their address, phone number and postcode?
Of course - the address is Jesus Lane cb58bs and the phone number is 01223452587
Can you give me another idea -- just to have a choice?
Sure there are several churches in the area.  Holy Trinity church is interesting.  Also, if you are not interested in churches, old schools on Trinity Lane is nice.
I am interested in the old schools on Trinity Lane, can you give me the information of one? 
Sure, Old Schools is located on Trinity Lane, their postcode is cb21tt and their phone number is 01223332320. Their entrance fee is free. Can I help you with any other information?
Nope, that's all I needed. You've been quite helpful.
Okay great, have a good day!
