U: I am looking for an expensive place to eat.

S: We have plenty of high end expensive options in Cambridge, 57 to be exact.  Anything I can do to narrow down your options?

U: Are there any Japanese restaurants in the centre of town?

S: There are not any expensive Japanese restaurants in the centre, but there is a moderately priced one. Would that work for you?

U: Could you check again for an expensive one?

S: It is wagamama, would you like a reservation?

U: Is yakitori on the menu there?
S: Yes, Wagamama offers yakitori and it's consistently extremely well reviewed. Shall a book a table for you?
