U: I am planning a trip to Cambridge and am looking for a hotel.

S: There are at least 9 hotels in the area. What price range would you like?

U: Moderate price range. And a 4 star rating, please.

S: I'm sorry, we don't have any hotel rooms that meet those requirements.

U: I need a place with wifi.

S: I have 2 hotels in the moderate price range with free wifi and 2 star ratings in the north location, would you like one of those?

U: yes and book it for me and I need postcode

S: would you like the ashley hotel, cityroomz, or lovell lodge?

U: Which of those have the strongest, most reliable internet service?
S: The internet speed at the Cityroomz is unknown while that at each the Ashley Hotel and Lovell Lodge are frustratingly slow.
