U: I want to eat someplace with unusual food. Price is no object. What can you suggest?

S: I'm sorry, there is nothing meeting your criteria. What other type of cuisine  would you like?

U: Hmm.  I'm not sure.  It needs to be expensive, and I really had my heart set on unusual.

S: There are no restaurants anywhere in Cambridge that describe their cuisine as "unusual." Would you like to broaden your search criteria?

U: Then find a European one.

S: I have 5 european restaurants to choose from. I have options in the centre, north and west. Which would you prefer to dine in?

U: I would like one in the centre area, please.

S: How about Eraina, which serves European food and is located in the centre of town and is in the expensive price range?

U: Do they serve pierogi there, and is it highly rated?
S: Eraina does serve pierogi, but the reviews are mixed. Would you like me to look for something else fo you?
