Hello! I am looking for an expensive guesthouse type hotel. Any ideals ?
Sorry, but none of the guesthouses in Cambridge fall into the expensive price range.
I need a guesthouse with free parking and a 4 star rating.
I have many options.  What area of town would you like?  That should help me narrow it down.
The area doesn't matter, but are any of them considered cheap?
Yes, there are 7 cheap guesthouses in that area.  Were you looking for any other specific requirements? 
recommend any and find me its  postcode
Allenbell. Postcode is cb13js. Is there anything else?
Yes, I'm also looking for a Chinese place in the south?  Do you know of anything?  
There are three Chinese restaurants in the south, may I recommend The Good Luck Chinese Food Takeaway? They are a price range of expensive.
I need the price to be the same as the hotel, so I need a cheap restaurant as well. Are there any that fit this criteria?
Yes, what kind of food are you looking for?
I feel like chinese would be good.
I would like to get a table at "the lucky star".
