i am looking for a place to dine. The restaurant should be in the cheap price range and should be in the west.
{"__type": "Inform", "entity": {"__type": "Restaurant", "area": "west", "choice": "two", "food": "Vietnamese", "name": "Thanh Binh", "price range": "cheap"}} {"__type": "Offer", "entity": {"__type": "Restaurant"}}
The two cheap places in the west are La Margherita, which serves Italian food, and Thanh Binh, which is Vietnamese fare. Do you have a preference?
