U: Hi, I'm looking for some information about places to go in Cambridge.

S: Sure, what type of attraction are you interested in?

U: I would like to see architecture and need the area, address and entrance fee.

S: How about old schools? It is located in the centre area.

U: Great. Let me get the address and entrance fee please. I see it's in the centre.

S: Old Schools is located on Trinity Lane and there is no entrance fee. It is completely free. Do you need help with anything else today?

U: I'm looking for someplace in the center to stay as well

S: I have 5 locations in the centre of town. Do you have a price range?

U: Anything with a 0 star rating? I want a super trashy place

S: Well, we have two options that meet your needs. El Shaddai is a cheap guesthouse and Cityroomz is a moderately-priced hotel. Both in the Centre. Would you like more information?

U: Can you pick one that is centrally-placed and accessible?
S: Overall, the El Shaddai has a really nice location compared to Cityroomz. Would you like to make a reservation there?
