Yes do you have a preference for area of town or price range?
Can you help me find a restaurant the has Indian cuisine? I'd like it to be in the cheap price range and any area of town.
{"__type": "Request", "service": "restaurant", "values": ["area", "price range"]}
{"__type": "Inform", "entity": {"__type": "Restaurant", "area": "north", "choice": "three"}}
There are four, one in the north and three in the centre. Would you like a recommendation?
