I'm looking for cheap places to eat in the centre of the city.
Okay, there are fifteen restaurants in that area within the cheap price range. Do you have a preference on the cuisine that is served? 
Not really.  Which is your favorite?
Chinese would be a good choice. Would you like me to book one for you?
Yes, for 6 people, 12:15 on Wednesday. Reference number please.
I'll book you at Charlie Chan. In my opinion, its the best! Your booking was successful. The table will be reserved for 15 minutes.
Reference number is : W3TZFF5S.
I would also like a place to stay. I would like a cheap 0 star hotel in the centre.
el shaddai is a 0 star guesthouse in the cheap pricerange. Does this work for you?
Is there not a hotel? 
I'm sorry, there are no cheap 0-star hotels in the centre area of the city.
How about a guesthouse with 0-star and cheap?
The El Shaddai is the only one. Would you like to book a room there? Or maybe you need some more information? Or we could try another part of town.
More information please.  I'd just like the address and postcode for El Shaddai.
There are no hotels in El Shaddai that have 0 stars and are cheap.
