Hi, I'm looking for a cheap place to sleep, please.
What area of Cambridge will you be staying in? We have multiple hotels to choose from. 
It doesn't matter, should be cheap and has four stars.
You're in luck, I have 6 guesthouses and 2 hotels that are cheap with a 4 star rating. Would you be interested in booking a room?
Yes, but the place needs to have free wifi as well.
I would recommend the four-star Alexander Bed and Breakfast.  It is a cheap offering in the centre and it has wifi. 
do they have free parking?
They do, they are located in the centre. Would you like me to make you a reservation?
Yes, I am ready for a reservation.
I will just need number of people staying and number of nights and your arrival date.
Actually, I just need the address of the hotel.
Their address is 56 Saint Barnabas Road. Anything else I can help with? 
I looking as well for a restaurant, in the same price range as the hotel. Located in the centre.
There are 15 different restaurants that meet that criteria, is there a type of food you're interested in to narrow your choices down?
pick one for me and book for 2 people at 12:00 on Wednesday.
Charlie chan is a nice place I will book it for you
