Hi, I want an expensive restaurant. East part of town please.
Royal Standard is a Gastropub in East. Is this OK?
is there any other expensive restaurant in east? 
Yes there are four other options. What kind of food would you like?
It doesn't matter, just not Gastropub.
May I recommend the Grafton Hotel Restaurant, then?  They're very British, very expensive, and located in the east part of town.
That sounds like something I would enjoy. Could you give me the address and phone number?
Certainly. The Grafton Hotel restaurant is at 619 Newmarket Road Fen Ditton and the number there is 01223 241387. Can I be of further assistance? 
Thank you, goodbye.
