i would like some south african food that is not too expensive .
{'service': 'restaurant', 'act': 'request', 'slot_name': 'food', 'value': '?'} {'service': 'restaurant', 'act': 'nooffer', 'slot_name': 'none', 'value': 'none'}
unfortunately there are no restaurant -s available that fit that criteria . is there another type of cuisine you might be interested in eating ?
