U: I'm looking for an expensive vietnamese place to eat, can you help me find one?

S: It doesn't look like there are any expensive Vietnamese restaurants. Would you like me to look for a different cuisine type or price range?

U: Are there any British food joints?

S: Graffiti is in the west part of town in the expensive price range, would you like to book that?

U: Yes, please book a table for 6 on Thursday.

S: What time shall we make that booking for?

U: Make it for 11:15 and please give me a reference number.

S: Alright, your table for 6 has been booked for Graffiti for Thursday at 11:15. Is there anything else I can do for you?

U: Do you know if the Graffiti serves alcohol?
S: While the food may be considered mediocre at Graffiti, the alcoholic drinks have mixed reviews overall.
