I am looking for an Afghan restaurant in the expensive price range.
There are none in that range, perhaps something else?
Okay, how about mexican food?
Chiquito Restaurant Bar fits that criteria. Would you like to make a reservation?
Yes, please. 7 people at 18:30 on tuesday.
Unfortunately we can not book you for that date and time. Would you like to try another date or time perhaps?
How about 17:30 instead? 
That's a better time, your reference number is IV21ENWM and the table will be held for you for 15 minutes. Is there anything else you need?
Yes, I need a place to stay with free wifi. The hotel should have a 0 star rating. Do you have anything like that?
Sure, there is one option. CityRoomz, shall I book a room for you?
Is that expensive?
It is in the moderate price range.  If you give me your date of arrival, number of guests, and length of stay, I can try to make a reservation for you.
I need one that is in the expensive price range. 
I'm sorry there are no hotels in the expensive range with a 0-star rating, the lowest rating for that price range is a 2-star hotel.  Are you interested?
How about a 4 star expensive place to stay that includes free wifi? Can I have the postcode, hotel type, and address of one that meets that description?
There are 2 that fit that criteria. One is in the West and the other is in the Centre. Which is better for you?
I don't care about the area.  Can you pick one and give me the postcode, hotel type, and address please?
Try University Arms Hotel in Centre. It is close to alot since it is right there on Regent Street. Postcode is cb21ad. Anything more you need today?
No thank you, that's everything I need! 
Alright, thanks for using Cambridge TownInfo centre, have a great day!
