Hello, I'm traveling to Cambridge from Stansted Airport on Saturday and need to find a train.
Great! One of these trains should work, thank you and goodbye 
Um, one of what trains should work? Hello?
I'm very sorry for the confusion, there are 19 trains travelling to cambridge on saturday, do you need to depart or arrive at any particular time?
I would like to depart stansted airport saturday and arrive in Cambridge by 12:00. Could you also let me know the cost?
All trips arriving by 12:00 cost 8.08 pounds. Is there a specific time you would like to depart?
No, instead I'd like to find a gastropub restaurant in the centre. Can you help me with that?
Yes definitely. I have 3 to choose from. Some are expensive and one is in the moderate price range. Do you have preference/
No.  Just choose one and give me the phone number and address please.
No problem. The Backstreet Bistro is at 2 Sturton Street City Centre. They're phone number is 01223306306. Is there anything else I can help you with today?
I also need to know what the price range is for this restaurant.
This restaurant is expensive.  Can I help you with anything else?
That will be all. Thank you for your help.
Not a problem! Have a great day now!
