U: I'm looking for an expensive restaurant in the centre of town.

S: We can narrow down our selection for you if we know the Restaurant chain and the kind of Food you prefer?

U: I'm open to any kind of food. I'm looking for something in the centre and on the expensive side.

S: There are a lot of good choices like that. I can recommend The Cambridge Chop House if British food appeals to you. Would you like me to book you a table?

U: Do they have a quality cornish pasty on the menu?
S: Yes, the Cambridge Chop House does serve Cornish Pasty. Would you like to know anything else about them?
