I need to find a train to Cambridge on Sunday.
Where will you be coming from?
I'm leaving from London Kings Cross. 
There are 10 trains that fit your criteria. Do you have a leave at or arrive by time preference?
It needs to leave after 14:30. I need a booking for 2 people. 
I have a train that will leave at 15:17 and arrive in cambridge at 16:08. Would you like me to book that for you?
That works for me. I need the reference number.
I was able to successfully book your tickets.  The reference number is 02BPMPU4 and the total is 37.76 GBP which is payable at the station.  
Thank you! Could you also suggest a museum to visit in the centre? 
There are 11 museums in the city centre. Are you interested in art, antiques, technology, archaeology, science?
Perhaps one without an entry fee?
Castle Galleries is located in the Centre and has free admission.
That sounds perfect.  Can you please give me the phone number, address, and postcode?
The phone number for Castle Galleries is 01223307402, the address is unit su43, grande arcade, saint andrews street, and the postal code is cb23bj.
Thank you so much for your help! 
No problem, is there anything else you'll be needing from me?
No, that will be all. Goodbye.
It was a pleasure helping you with your planning today. I hope you have a great trip. Good bye!
