U: Yes, I am looking for a molecular gastronomy restaurant in the centre.

S: I am sorry. There are not matches. Would you like to try a different type of restaurant?

U: Do you have any molecular gastronomy restaurants at all?

S: I'm afraid not, none in Cambridge. Would you like a different cuisine?

U: How about an expensive thai restaurant?

S: There is one in the West part of town, and one in the Centre part of town. Which area do you prefer?

U: I would prefer one in the Centre part of town, do they have openings for tonight?

S: Bangkok City is a Thai restaurant that would meet your needs.

U: Is it laid back enough to drink beer and enjoy a bargain?
S: Reviews were mixed with drinks referred to as both affordable and overpriced. Do you have any other questions?
