Im looking for a restaurant in the north part of town in the cheap price range
The Royal Spice is a cheap Indian restaurant in the south. Would you like more information?
Does it serve bistro food?
No, I'm sorry. Would you prefer a cheap bistro in the north, or some other qualifications? 
I would settle for British. I'd prefer moderately priced, actually, and location doesn't matter. 
I would recommend Cotto. They serve British food and are moderately priced. Would you like their contact information?
What is the phone number?
Cotto's phone number is 01223302010. Is there anything I can help you with? 
No, thank you, that is all I need.  Goodbye!
Good bye. Thank you for contacting the Cambridge restaurant system.
Goodbye.
