I want to dine in a place in the west. 
There are many restaurant options available to you. What type of food would you like to eat and what is your price range?
I would like a restaurant that serves eritrean food and in the expensive price range. 
Would you like European food?
No.  I said eritrean food.  Do yo have something?
I don't have anything that meets those requirements. 
How about British food?
Yes I have three. When would you like the table reserved for and for how many?
Is one of those expensive? If so, book me a table there for Thursday for 8 people at 13:30 please. 
There's actually two expensive places, graffiti and travellers rest. Which would you prefer?
Travellers Rest sounds good.
ok the address is huntingdon road in city centre, the phone # is 01223276182, and the postcode is cb30df.  will there be anything else ?
I am also looking for a train from Cambridge on Wednesday.
what is your destination? 
Before I continue with the train details, was Travellers Rest booked? I didn't get a reference number.
My sincerest apologies for that. Yes, your booking is completed and the reference number is 64UQ7M3G
That is all I needed thank you. 
You're very welcome! Have a great day! Bye!
