i am hoping to find a french restaurant in cambridge .
{'service': 'restaurant', 'act': 'request', 'slot_name': 'area', 'value': '?'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'price', 'value': 'expensive'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'choice', 'value': 'two'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'area', 'value': 'north'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'area', 'value': ' in the centre'}
there are 2 . both are expensive . 1 is in the north and 1 is in the centre . do you have a preference ?
