The input is a conversation between an automated system and a user looking for suggestions for pubs, restaurants and coffee shops in Cambridge. In the dialogue, the user may provide some criteria for the type of place they want such as price range, cuisine, etc. Given such a dialogue, output the price range the user if looking for which can take one of four values: Cheap, Moderate, Expensive and Don't Care. 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.
One example: System: 'Thank you for calling the Cambridge Information system. Your call will be recorded for research purposes. You may ask for information about a place to eat, such as a restaurant, a pub, or a cafe. How may I help you?'
User: 'im looking for a moderately priced coffee shop'
System: 'Are you looking for somewhere near a particular venue? For example, Cambridge Contemporary Art, Great Saint Mary's Church, or Primavera.'
User: 'no im not'
System: 'Cafe Eleven, which is in the moderate price range, is an outstanding cafe.'
User: 'can i get the phone number and the postcode'
System: 'The phone number of Cafe Eleven is 01223369157. It's in the area with the postcode CB1 1DG.'
User: 'thank you goodbye'
