I'm looking for a train that departs from birmingham new street. It should arrive by 18:30.
{"__type": "Inform", "entity": {"__type": "Train", "arrive by": "18:23", "choice": "one"}} {"__type": "Request", "service": "train", "values": ["day"]}
There is one arrives at 17:23 and another at 18:23. What day are you traveling?
