U: am looking for a restaurant. The restaurant should be in the west and should be in the cheap price range

S: I have two choices in that area and price range.  Would you prefer Italian or Vietnamese?

U: I would prefer Vietnamese.

S: Thanh Binh is a cheap Vietnamese restaurant in the west. Shall I book a reservation for you?

U: Do you know if it has a nice outdoor place for dining?
S: No, unfortunately it doesn't look like there is any outdoor seating offered at the Thanh Binh restaurant.
