i am looking for an expensive restaurant in the center of town .
{'service': 'restaurant', 'act': 'request', 'slot_name': 'food', 'value': '?'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'choice', 'value': '33'}
there are 33 restaurant -s that meet your needs . would you like to narrow your search by type of food ?
