U: I'm looking for a gastropub.

S: Okay, there are four gastropubs in cambridge. Are you looking for a particular area or a certain price range?

U: Yes, something in the centre of town please?

S: I have 3 gastropubs in the center of town. Does price range matter to you?

U: No, price range does not matter.

S: In that case, I recommend Backstreet Bistro at 2 Sturton Street City Centre. Would you like a table there?

U: Sounds nice.  Can you tell me if they have high chairs there?

S: No, Backstreet Bistro doesn't have any high chairs. Do you have any other questions or concerns I can address?

U: Does Backstreet Bistro serve alcohol?
S: Yes, the Backstreet Bistro serves alcohol, including wine and beers. Do you want to know anything else or should we make you a reservation?
