U: I'm looking for a place to dine in the centre that serves jamaican food.

S: I'm sorry, I'm not finding any place that serves Jamaican food in the centre of town.  Would you like to try another area?

U: That is fine, how about a place that serves Indian food?

S: There are several of those.  Do you have a price range you are looking for?

U: I have no preference in price range.

S: I have 9 different indian restaurants in the centre of town. If you are looking for a truly authentic experience, might I suggest The Golden Curry. They are expensive.

U: That sounds perfect. Can you book a table for me for tuesday?

S: Sure. How many people will be dining on Tuesday?

U: I need the reservation for 2 people for 14:30 for Tuesday.

S: Okay, your table is booked for the Golden Curry and your reference number is SYL7B9MN.

U: Are the portions big?
S: The Golden Curry offers large portion sizes, including their highly regarded Vindaloo. Is there anything else that I can do for you at this time?
