hi there . can you help me find a train from norwich to cambridge ?
{'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': 'several'} {'service': 'train', 'act': 'request', 'slot_name': 'leave', 'value': '?'}
there are several trains on that route . what time would you like to leave and depart ?
