U: I am looking for a nice bistro in Cambridge, moderately priced would be good.

S: unfortunately i don't have anything in that price range

U: There's nothing moderate in all of the centre area?  Or just bistro food?

S: We have 31 moderately priced restaurants in the center, just no Bistro, sorry.

U: Is there a gastropub in that area instead?

S: Yes, we have one and it's called The Cow Pizza Kitchen and Bar.  Would you like for me to book a reservation for you?

U: Do they serve alcohol?
S: Yes, they do serve drinks there with pretty good reviews on taste and prices. There are complaints that the selection is limited. Would you like to know anything else?
