U: i am looking for a place to eat in the centre that serves  creative food.

S: We have no restaurants that serve creative food anywhere in Cambridge. Can I find you a different style of restaurant in the  center?

U: What expensive restaurants are in the centre?

S: There are quite a few.  asian, british, african, or a gastropub are just a few choices. Do you have an idea of the cuisine you'd like to try?

U: I would like to try Italian food.

S: I have several. Would you like me to suggest one for you?

U: If you could, just go ahead and pick an expensive one. I'll need a table booked on Monday at 19:30. It will be 6 people.

S: How about clowns cafe? It's expensive.

U: Do they have a nice outdoor area for dining?
S: I'm sorry, Clowns Cafe does not have an outdoor dining area. Would you like me to find a comparable place that does?
