yes i am looking for a place to eat in south cambridge that is more on the expensive side . i would prefer vegetarian food .
yes there are 5 different place -s that serve 4 different types of food .
{'service': 'restaurant', 'act': 'request', 'slot_name': 'food', 'value': '?'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'price', 'value': 'expensive'} {'service': 'restaurant', 'act': 'inform', 'slot_name': 'food', 'value': 'vegetarian'}
unfortunately , there is no expensive vegetarian restaurant in that area . would you like to look for something else ?
