U: I am looking for a restaurant to dine in during my visit to Cambridge.

S: I would love to help! Any kinds of foods you'd prefer?

U: I would prefer something in the Centre area, that has a moderate price range, and serves Afghan food.

S: I'm sorry, but there are no Afghan restaurants in all of Cambridge. Would you like to try a different cuisine?

U: Are there any restaurants in the cenre that serve turkish food?

S: Yes we have 2 moderate priced options.  Anatolia or efes restaurant.  Do you have a preference?  I can book a table for you if you want.

U: Which one has a good portion of foods? I'd prefer that.
S: If you're looking for for portion sizes, Efes Restaurant is known for their generosity whereas Anatalois has a mixed opinion on their plate offerings.
