I'm looking to stay in a guesthouse in the east.
I'd be glad to help you find a guesthouse, are you looking for something moderately priced or would you like a cheaper option?
I don't care about price range, but I would like to have free parking.
I have a few listings for guesthouses, I will give you the listings for moderate prices as they will be nicer. 
Please include post code and phone number with the listings.
The Warkworth House's contact number is 01223363682. The postcode for them is cb11ee.  The other moderate priced is Carolina Bed and Breakfast, phone 01223247015 with postcode cb13nx. Anything else?
I am also looking for a restaurant. I prefer it to serve cuban food and i would like a moderate price range. 
There are no moderately priced Cuban restaurants in Cambridge, unfortunately. Would you like me to look up other restaurants in the moderate price range?
How about chinese food?
There are four chinese restaurants. Would you rather eat in the north or centre?
North is fine, what is the postcode for that?
In the north is the golden wok, the postcode is cb43hl.  Do you need more information on that or with anything else?
No, that is all I need at this time, thank you for your help.
Happy to be or service. Have a wonderful day!
