Given the task definition and input, reply with output. The input is a conversation between an automated system and a user looking for suggestions for pubs, restaurants and coffee shops in Cambridge.

Output cannot be any other value than the four values. Note that if the user asks for the prices of items provided at a pub, restaurant or coffee shop but doesn't mention the price range they are looking for then the correct classification will be Don't Care. If the user does not mention a particular price, the correct classification will be Don't Care.
