U: I am looking for an expensive restaurant in the centre.

S: I found quite a few. What kind of food would you like?

U: I'd like an expensive gastropub.

S: I have the backstreet bistro in the centre of town, does that sound good?

U: I'd like a place that service nice portions of food...does the Backstreet Bistro have that?
S: While the majority of Backstreet Bistro customers say the food is generously portioned, there was a comment that the small portions were a downside of the establishment. Would you like me to look into it a bit further to get more info on the food portions?
