U: Hello, could you please find me a place to dine?

S: Did you have a certain area or price range you would like to dine at?

U: The restaurant should be in the west and should serve expensive kosher food.

S: I do not have any restaurants meeting that description. Would you like to try a different type of food?

U: Do you have one that serves British food?

S: There are 2 restaurants that serve British food, the Graffiti and Travellers Rest. Would you like me to book one for you?

U: Sure, either as long as it is expensive and in the west.  Can you book a table for 1 on Tuesday at 17:45?

S: Ok, I have you booked at Graffiti on Tuesday at 17:45.

U: Does the restaurant offer outdoor seating?

S: Outdoor seating is currently available here. Will you be needing anything else?

U: Does the Graffiti serve alcohol?
S: Unfortunately, I don't have any records about the Graffiti. I can tell you that Traveller's rest does serve alcohol.
