I am looking to book a train.
I would be more than happy to help you find a train. Can you tell me where you will be departing from and where you would like to go?
I'm looking for a train that goes to leicester and arrives on sunday. The train needs to leave after 6:45 from cambridge.
Is there a time you need to arrive by?
I need to leave after 18:45, not the time I said before. 
I have five options for your requested time with the closest leaving at 19:21. Would you like to make a reservation?
Yes please. Book it for 5 people. What is the reference number?
Your reference number is P5XAHU9D. Is there anything else I can help you with?
Yes, I am also looking for a cheap place to dine.
I've got several choices for cheap dining.  Do you have a preference of area or food type?
Centre area, no food type preference, what do you recommend?
I have several options. How about the Dojo noodle bar? It's located at 40210 Millers Yard City Centre. 
Sounds great, I'd like to book for the same number of people at 10:00 on the same day.
Unfortunately booking at that time was unsuccessful, do you have an alternate time you'd prefer?
Please try 9:00 instead on the same day.
They are not open at 9:00 on sunday. May I suggest another establishment?
Are you quite certain you can't get me a table at 9:00?
I am certain. Their phone number is 01223363471, perhaps you can call and speak with someone. 
thank you I will call them
You're welcome. Is there anything else needed?
Actually, book that for me. Same number of people on the same day.
It appears to be booked up all day sunday. Can I recommend another restaurant that might be open that day?
Yes please do I am having no luck, I need the reference number then too.
I can do the j restaurant in the centre if that would be ok
Sure we can try to book that.
That doesn't seem to be working either.
Can you please locate another restaurant for me please that is accepting reservations on sunday.
I am sorry but on Sunday cheap restaurants in the centre are all completely booked. Is there something else I can help you with?
Please recommend the cheapest restaurant that is available and book it.  We need to eat!  Thanks!!!
Okay, the river bar steakhouse and grill can be booked at 9:00 on Sunday, I've booked for 5 people, the reference number is RFTEXMIX, is there anything else I can help with today? 
No, thank you. You were very helpful.
Thank you for contacting Cambridge TownInfo centre. Goodbye!
