hi , i would like to find a train from cambridge to leicester .
{'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': 'many'} {'service': 'train', 'act': 'request', 'slot_name': 'day', 'value': '?'}
certainly , there are many trains going that route . can you specify which day you would like to travel ?
