Can you help me find a restaurant that serves greek food and is expensive?
{"__type": "NotifyFailure", "service": "restaurant", "entity": {"__type": "Restaurant", "food": "greek", "price range": "expensive"}} {"__type": "Request", "service": "restaurant", "values": ["food", "price range"]}
I apologize but there are no expensive greek restaurants listed, would you like to try a different food type or price range?
