I am looking for a hotel in Cambridge.
There are over 30 places of lodging in the city. Would you prefer a certain part of town, or a particular type of lodging such as a guest house or hotel?
Just a 4 star guesthouse that has free parking please.
What area would you like the guesthouse to be in?
Do not care what area,it will be for 2 people and for 4 nights starting Wednesday. 
Would you like me to book you at the acorn guest house? It has free parking and it's a 4-star hotel.
Can we book it for 2 people for 4 nights?
I am sorry I couldn't get that booked for you perhaps another day or a shorter day possibly?
Could you try it for one night only?
Yes booking is available for one night,would you like me to place it?
Yes please, and I'll need the reference number.
Ok I have made that reservation for you the reference number is OXWO0RWD.
I am also looking for an expensive mediterranean restaurant in the west.
I'm sorry there are no matches for what you are looking for. Would you like something else?
Yes, how about a restaurant that serves Indian food?
There are 5 Expensive Indian restaurants in the west. I recommend Cocum. Would you like me to make a reservation?
Cocum sound fine, but I just need the postcode, please.  No reservation.  
Of course.  The postcode for the Cocum is cb30ah.  Is there anything else I can help you with?
Thank you! That's all I need. Goodbye!
Enjoy your meal!
