U: I am looking for a Chinese restaurant in the cheap price range.

S: There are 3 restaurants in centre and one in south. Which area are you most interested in?

U: Let's try the one in the south. Are there openings on Tuesday?

S: I would need to know what time and for how many people in order to check on Tuesday's availability.

U: It will be at 15:30 on Tuesday and there will be 4 people.

S: I was unable to book. Do you want to book another timeslot?

U: How about 14:30 instead?

S: Booking was successful to dine at the Lucky Star. Table will be reserved for 15 minutes.  Your reference number is : M0OW1EI5.  Anything Else?

U: Is that place decorated nicely?
S: The Lucky Star is decorated using a Chinese theme. Is there anything else that I can help you with today?
