Hello, I'd like some information about colleges in the area that are interesting to visit
Which area do you prefer?
I don't care, do you have any suggestions?
I suggest Christ's College in the center area. Entrance is free.  The address is Saint Andrew's Street, the phone is 01223334900.  Would you like the postcode?
Thanks. I also need  train going to cambridge on tuesday.
Where would you like to depart from?
I need to leave from Leicester, and the train should arrive by 10:45 please.
Ok, there are 4 trains that meet that criteria, what time would you like to leave by?
I don't care when I depart, please book me one that is closest to the 10:45 arrival in cambridge. I just need one ticket. 
Certainly, I have booked TR4734 arriving at 09:54 your reference number is  VZ5HHW3E. Can I help with anything else?
That will be all, thank you. Have a great day.
You're welcome!  Have a great day!
