i would like to book a train . after 19:00 on friday from leicester to cambridge .
ok , let s narrow this down a bit . where are you traveling to , what day are you traveling , and at what time ?
{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '20:54'} {'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': '5'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '19:09'} {'service': 'train', 'act': 'select', 'slot_name': 'none', 'value': 'none'}
okay great , there are 5 trains leaving after 19:00 . the earliest being 19:09 and arriving by 20:54 . would that work for you ?
