U: What sort of dining does Cambridge offer in the centre, in the moderate price range?

S: There are 21 different choices. What kind of food are you looking for?

U: I would like some christmas food.

S: I'm sorry. I could not find a restaurant that meets that criteria.  Would you like to try something else?

U: How about somewhere with Lebanese food?

S: Yes, there is a moderately priced Lebanese restaraunt in the centre named Ali Baba.  How does that sound?

U: Does the restaurant have a nice Middle Eastern decor?
S: Guests have commented that Ali Baba was not very decorated, a bit outdated, mediocre, and kind of a let down. Would you like to book a table or should I try somewhere else?
