U: Hi.  Could you help me find an expensive restaurant that serves Catalan food?

S: Unfortunately, I don't show anything available meeting those requirements. Can I try a different price range or type of cuisine for you?

U: How about something in the centre of town

S: I was able to find bedouin in the centre of town in the expensive price range.

U: The Bedouin serves Catalan cuisine?

S: The Bedouin serves African food.

U: Do they provide generous portions?
S: There are mixed reviews about the portion sizes at their restaurant. Some people thought that the portions were large and others thought they were too small.
