I need to find a barbeque restaurant in the centre of town.
{"__type": "NotifyFailure", "service": "restaurant", "entity": {"__type": "Restaurant", "food": "barbecue"}} {"__type": "Request", "service": "restaurant", "values": ["food"]} {"__type": "Offer", "entity": {"__type": "Restaurant", "area": "center of town"}}
There are no barbecue restaurants in town. Would you like to search for a different type of restaurant in the center of town?
