I'm looking for a restaurant the serves austrian food in the centre.
I'm sorry, but no restaurants match your criteria. Would you like to broaden your search?
What about something in the expensive price range? 
There are 33 expensive restaurants in the center of town, but no austrian ones. In fact, there are no austrian restaurants in all of cambridge.
Ok, how about an expensive Italian restaurant around the centre?
Would you like to book don pasquale pizzeria? It matches all of your latest criteria.
Yes.  I'd also like their phone number please.
Don Pasquale Pizzeria's phone number is 01223350106, what date, time, and number of people would you like to book?
