I'm looking for a guesthouse to stay at that has a 4 star rating. Can you help?
Sure, we have many. Are you looking for anything else specifically?
Yes, I need internet and free parking. 
To help narrow this down, can you tell me what area of town you'd like most?
Yes, I would like to be in the north. Oh and I would like to be in the expensive price range.
unfortunately i don't have anything that meets all those criteria. is there anything you'd like to change?
No I will figure something out 
Is there something else I may be able to help you with today?
I lied. I don't need free internet and parking. 
One more time let me know exactly what you need by looking at what you wrote down on your right, so we can book you.
i need an expensive hotel in the north
There are no hotels that meet that criteria. Would you like to search for something else?
A moderate price range. I need 2 nights beginning Monday and the reference number. Also looking for a train, same people same day as hotel and reference number as well.
There are 9 options. Do you prefer a guesthouse or hotel? 
I prefer a guesthouse please. I only need it for myself for 2 nights starting from monday.
May I recommend the Acorn Guest House at 154 chesterton road. Would you like me to book a room for 1, for 2 nights starting Monday?
Yes, please. I would also like the reference number.
Would you like me to book it for you ?
