I'm looking for an expensive restaurant in the west part of town.
I have found nine restaurants matching your request. Is there a specific type of food you would like?
The restaurant should serve british food.
I think Griffiti would serve you well. Would you like to book a reservation?
Yes please and I will need their phone number for reference please.
Certainly, the phone number is 01223277977. How many people will be dining?
I'm not sure yet. Can you tell me what trains are traveling to cambridge on thursday?
There are five trains traveling on Thursday. The first one leaves at 05:17 and the last leaves at 13:17. What time do you want to leave?
I need to arrive from Stevenage by 14:30, if possible.
There are 4 trains, one is TR1661 and arrives at 12:43, would you like to book that?
Do you have any arrive closer to 14:30 time period? If not I will just need the train ID and departure time. 
There is one arriving at 14:43 the TR2833 otherwise the closest one arriving prior to 14:30 is the one I mentioned arriving at 12:43. 
Great, that's all I need. Thank you for your help today!
Have a great trip!
