I apologize but there are no expensive greek restaurants listed, would you like to try a different food type or price range?
Can you help me find a restaurant that serves greek food and is expensive? Do you have any Indian restaurants?

{"__type": "Inform", "entity": {"__type": "Restaurant", "choice": "14", "food": "indian", "price range": "expensive"}}
We have 14 indian restaurants in the expensive category. Do you have any more information to narrow down the search?
