I am looking for a park to go visit.
There are 5 parks here in Cambridge, did you have a particular area of town you'd like?
No, not really, do you think you could recommend one?
Yes. Cherry hinton water play is located in the east. Would you like anymore information?
Yes. Can I please have the phone number and address?
Certainly. The park is located at Cherry Hinton Hall, Cherry Hinton Road. The phone number is 01223446100. What else can I do for you?
I am also looking for a four star hotel in the south.
There are no four star hotels in the area, could I look somewhere else or another star rating?
Are there any four star guesthouses in the South?
There are no four star guesthouses in the South. Is there a different type of four star guesthouses that you are looking for? 
How about just any guesthouse in the south, then?
There are two guesthouses that meet your criteria. Would you rather have something in the price range of moderate or cheap?
I guess moderate would be better.
I would recommend the Aylesbray Lodge guest house. It's moderately priced and located in the south with free wifi and parking. Would you like assistance booking there?
OK. Yes, can you book the hotel?
Of course. I just need to know your arrival day, how many nights you'll be staying, and the number of people.
It doesn't matter. None of those matter.
I apologize but it in order to assist you with booking I would need to know how many in your party and the day and length of your stay. 
I don't need to book a room. I just need the phone number, postcode and price range of the guesthouse you found.
Sure, aylesbray lodge guest house phone number 01223240089, postcode cb17sr and price range moderate.
Can I also book a taxi with you to leave that hotel at 23:30 going to the attraction we discussed?
I have confirmed your taxi, a blue audi will be picking you up. Their contact number is 07496908373. Can I help with anything else?
No that is all, you have answered all my questions
I'm glad we could be of service. Have a nice day.
I hope you have a nice day as well.
Thank you, enjoy your stay in Cambridge.
