I am looking for a restaurant to dine in during my visit to Cambridge.
I would love to help! Any kinds of foods you'd prefer?
I would prefer something in the Centre area, that has a moderate price range, and serves Afghan food. 
I'm sorry, but there are no Afghan restaurants in all of Cambridge. Would you like to try a different cuisine?
Are there any restaurants in the cenre that serve turkish food?
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.
I'm not ready for a reservation, but can I get the address for Anatolia?
sure! it's 30 Bridge Street City Centre	
I'm sorry I also need the post code. 
The postcode is cb21uj.  What else can I help you with today?
I'm also looking for somwehere to stay, is there anything with a star of 0? 
I have not found anything with a star of zero.
