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: Is this a interesting restaurant to look at through a window?
S: The view from Anatolia overlooking Main Street is nice while the sights at Efes Restaurant are somewhat lacking as its located in a strip mall.
