Good morning!  I need to take a train to Cambridge on Tuesday.
I'm sure we can accommodate you. Where are you departing from? 
I'm looking to leave from ely and arrive by 12:15
Okay, the TR3412 leaves at 11:35 and arrives by 11:52. Would you like me to book tickets?
Yes, that would be great. I would like to book a ticket for 4 people.
I booked your train ride. Your reference number is CRLMATVB and it will cost 13.2 GBP when you go to the station.
Thanks. I am looking for an asian oriental restaurant in the centre. Do you have any?
I have options ranging from cheap to expensive. If price is no issue, Kymmoy is the best.
I need something moderately priced. 
J restaurant meets your requirements.
Sounds good. Can I have their address?
Yes. The address is 86 Regent Street, City Centre. Can I book a reservation for you?
No, I'm just figuring out my options right now.  You have been very helpful, that is all I need for today.  Bye.
Let me know if I can help more.
