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: I'm a big Shepherd's Pie snob and want only the best restaurant.
S: Yes, the food at Graffiti is fantastic and they do offer a great Shepherd's Pie. Shall I check on availability for you?
