I am looking for a restaurant that is moderately priced and in the north part of town.
The Golden Wok is in the north part of town and is in the moderate price range.
No I am not interested in the Golden Wok, is there anything else?
The Nirala is also located in the north and moderately priced.  It serves Indian food.
Great! Can I have the phone number and postcode please?
The nirala is located at 7 milton road chesterton. Its phone number is 01223 360966 and the postcode is CB41UY. Is there anything else I can help you with?
