U: I'm looking for a moderately priced resturant in the centre of town.

S: I found 21 restaurants available, do you have a type of food you would prefer?

U: I would like lebanese food.

S: How does Ali Baba? I recommend it. Would you like for me to book a table?

U: Do they have live music?

S: No, there is no live music at the restaurant. Can I answer any other questions for you?

U: Does the restaurant serve alcohol?
S: Yes, they do, and while the drinks are a bit pricey, reviews are very positive. Would you like to make a reservation?
