There are 15 cheap restaurants available in the Centre area. Are you looking for a particular type of food cuisine?
I'm looking for a cheap restaurant in the city centre. I'm not looking for anything in particular, could you choose one and book a table at 13:45 for 2 on Wednesday?
{"__type": "Inform", "entity": {"__type": "Restaurant", "area": "Centre area", "choice": "15", "price range": "cheap"}} {"__type": "Request", "service": "restaurant", "values": ["food"]}
{"__type": "NotifyFailure", "service": "entity"} {"__type": "Request", "service": "entity", "values": ["book time"]}
Unfortunately, that time slot isn't available. Would you like to try a different time?
