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: Yes, let's book a table for 6 people at 14:45 on tuesday.

S: Alright, your reservation is made with reference number V76UTC2C. Can I help you with anything else?

U: i also need a hotel room for two nights and 1 person and must have free parking

S: What area do you need it to be in?

U: In the centre please

S: What price range?

U: Not price specific but I want something 0 star.

S: I think El Shaddai would be perfect for you.  It's in the centre of town, 0 star, and has free wifi and parking.  Can I book for you?

U: Is there a hotel within the same price range in this area with a better rating?
S: I honestly can't tell you that because I don't have the information available to me. Do you need help with anything else?
