U: I'm looking for an expensive restaurant in the centre.

S: I have many. Could we narrow it down a bit by the type of cuisine you may be looking for?

U: I'd like to try Indian cuisine. I a table for three  at 15:45 on Monday.

S: I can't seem to find a table that is available at that time. Would you be interested in trying a different day or a different time slot?

U: Yes, let's try for 14:45 instead.

S: Booking at Curry Garden was successful. The table will be reserved for 15 minutes. Reference number is : 3HVUQFTT. Is there anything else I can help you with?

U: Will you be able to make that table in a nice outdoor seating section?
S: If you're searching for an establishment with a nice outdoor seating section, the Curry Garden does offer such an area for its guests.
