U: I'm planning a trip to cambridge and need a place to dine. Can you find something that serves jamaican food in the centre?

S: There are no Jamaican restaurants in the centre. Would you like to try another area or another food type?

U: Are you sure? It should be expensive.

S: I'm sorry, there doesn't seem to be a Jamaican restaurant in Centre. Would you like me to look for something else?
