U: I need a place to dine on Indian food. Centre of the town please.

S: Sure, is there a specific price range you are looking for?

U: No. Just a place that can accommodate a table of 8 at 17:15 on Sunday.

S: You have a reservation at Saffron Brasserie for 8 people on Sunday at 17:15. Reference #Q7C8EX21. Can I help you with anything else today?

U: What portion sizes does this restaurant offer?
S: The portions at the restaurant are large. Do you need to know anything else or do you need any more from me?
