I am looking for a place to eat that's expensive and serves Belgian food.
I'm sorry, we don't have any Belgian restaurants. Would you like to try a different type?
How about somewhere expensive in the centre?
no such restraunts too
How about a gastropub restaurant?
I have two, the backstreet bistro and the slug and lettuce. Do you have a preference between the two?
Can you book a table at the Bistro for me? 4 people at 13:30 on Sunday, please.
Booking was successful. The table will be reserved for 15 minutes.
Reference number is : NSLKEI1G.
Thanks! I also need a train from Cambridge to Ely, please.
what time will you be departing?
I want to leave after 10:30 on Monday. 
The TR8089 meets your criteria. Would you like to book tickets?
Yes, what time do I need to be at the station?
I should be asking you what time you need to be at the station. 
I just need the arrival time and price.
The arrival time for train TR8089 is 12:07, and it will cost only 4.40 pounds. Is there anything else I can help with?
That was everything. Thanks very much!
You're welcome, have a good day.
