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

S: There are 4 restaurants to choose from. Do you have a part of town you prefer?

U: Yes, I'd like the restaurant to be in the centre.

S: I'm sorry, there are no restaurants that match all of your criteria. Would you like to look for a different type of cuisine, area, or price range?

U: How about a chinese restaurant in the centre?

S: Ok, I have 3 restaurants that meet your requests, would you like me to book one of them for you?

U: Yes, I need a table for 5 people on Tuesday at 12:30. Could I have the reference number as well for that?

S: Booking was successful. The table will be reserved for 15 minutes. Your Reference number is Q9MQW1Q4.

U: Does that restaurant serve alcohol?
S: Yes, the Lang Hong House has a good selection of drinks to choose from. There are some mixed reviews on the prices and quality of the drinks. Would you like to know more about them?
