I am looking for a british restaurant please.
I have many different options I can recommend to you, but could you tell me what area or price range you prefer?
I would like it to be in the West and be expensive.
Graffiti is in the west part of town and the expensive price range.
That sounds good. What is the postal code there?
The postalcode for Graffiti is cb30lx and it is located at Hotel Felix Whitehouse Lane Huntingdon Road. Would you like me to book that for you?
No, I can book it later, thanks.  Can you help me find a train that leaves Cambridge on Wednesday?
Certainly.  What is your desired destination?
My destination is stansted airport. 
Sure, trains leave hourly staring at 05:40 and cost 10.10 pounds per ticket.  Can I book a seat for you?
I need to leave after 15:45. 
Ok, I have train TR2912 departing at 16:40.  Would you like me to book this for you?
No need to book it. But, can I get the travel time and what time it will get me to the airport?
The travel time is 28 minutes and you will arrive at the airport by 17:08.  Is there anything else I can help with?
That is all, thank you very much.
You're welcome!  Enjoy your tacos! Goodbye
