I'm looking for an expensive place to dine in the centre. 
There are many, can I get an area you are looking for the restaurant to be in?
Yes I will like it to be in the center of Cambridge.
I'm sorry, "area" was in my head because you already mentioned it, but I meant to ask what sort of cuisine you might like.
I would like it to serve European food and be expensive please.
How about Eraina located on Free School Land, City Centre?
Thats a very unique name, and sounds like something I would like to try.
Would you like for me to make a reservation for you?
I just need the phone number and post code please?  Can you also help me book a train from Bishops Stortford to Cambridge on Saturday arriving before 15:15?
Eraina's phone number is 01223368786, and the postcode is cb23rh.
Thank you very much, now I just need to get the train ID, departure time, and price of a train that's leaving Bishops Stortford and going to Cambridge by 15:15.
Absolutely. There's train TR5108 leaving Bishops at 13:29. It costs 8.08 pounds. 
Wonderful. Could you please give me the train ID, the departure time, and the price? 
TR5108  is the train ID anything else?
No thank you, that is all I needed. Goodbye!
You're welcome, have a lovely day!
