Hello, I'm looking for information about restaurants in Cambridge. They should be located in the Centre and ser Gastropub food.
Would you like an expensive place? Or moderate? 
Just a gastropub located in the center for 8 people at 12:00 on wednesday please
Sorry, none of the restaurants are available for that time and date. Perhaps pick another time?
How about at 11:00 instead?
Good news! I  was able to book a table for you at Backstreet Bistro on Wednesday at 11:00 for 8 people. Your reference number is 75F4S49D. 
Excellent. I'm also looking to book a train too.
I can do that for you, where do you need to go?
I'll be coming to Cambridge from Broxbourne, on the same day as the restaurant booking please.
I have 5 options that will have you arrive before your restaurant reservation.  The train leaves every hour beginning at 5:32.  Would you like me to book a ticket?
Yes, please book 8 tickets on the last train to arrive before 8:30.
Booking was successful, the total fee is 143.19 GBP payable at the station . Reference number is : EJJGOJ29.
Okay thank you.  That is all I needed. 
Have a great dinner and a lovely train ride!
