U: I am looking for a restaurant that serves indian food.

S: In what area of town would you like to eat?

U: In the centre of town please. I am looking to stay in the expensive price range.

S: Great, there are 6 restaurants that meet your criteria. I would suggest Curry Garden. Can I book it for you?

U: Does it have nice interior decorations?
S: The decor is not very exciting at Curry Garden, but the food seems to make up for it. Are you still interested?
