U: I am looking for a place to eat in town centre.

S: There are 69 different places to choose from. What type of food would you like?

U: It doesn't matter as long as it is cheap.

S: I have 15 restaurants that match your description? Is there a specific cuisine you would like?

U: I don't care about the cuisine. Would you book a table for 4 people at 16:00 on Wednesday?

S: I made a reservation for you at J Restaurant at 86 Regent Street.  Reference Number UWVRJC3M.  Can I help you further today?

U: Do they have great service?
S: Yes, I've heard really good things about their waitstaff. Can I answer any more questions for you today?
