hi ! can you tell me what trains are available on friday after 18:30 ?
{'service': 'train', 'act': 'request', 'slot_name': 'depart', 'value': '?'} {'service': 'train', 'act': 'request', 'slot_name': 'dest', 'value': '?'}
certainly , but first i need to know where you are departing from and what your destination is .
