I'm looking for a restaurant in the east.
There are nine restaurants in the east. Do you have a price range in mind?
I don't have a price range but I am looking for asian oriental cuisine. Is that possible?
I am sorry there is nothing that meets that criteria. Is there another type of food or area you would be interested in?
How about British food?
I would recommend you try Grafton Hotel Restaurant.  As requested it is in the east and serves British food. 
Thanks, will you please book a table for 7 people on thursday at 13:00?
