U: I would like to find a restaurant in the expensive price range that is located in the city center.

S: There are 33 expensive resturants in the city center.  We could narrow it down more by food type. What type of food would you like?

U: I do not care about that.

S: Bedouin serves African food, is in the center, and in the expensive price range. Do you want me to book this restaurant?

U: Is the outdoor dining nice?
