U: Ah... just pick one that you recommend and do a reservation for 6 at 14:45 on Saturday.

S: I've reserved a table for 6 at ugly duckling at 14:45 on Saturday. Your confirmation number is G6RS8PAR.

U: am also looking for a place to stay. The hotel should include free parking and should include free wifi

S: Sure, can I narrow down your preference a bit?  Is there a part of town you prefer?

U: I'd love it if we could stay in the centre of town. Also, I would like it to be three stars.

S: Great.  Gonville hotel should meet your needs.  Would you like me to book it for you?

U: Can you let me know whether the Gonville Hotel will give me a lot for the price I'll spend?
S: It's a very nice place, but some guests felt the price was a bit high. Are you still interested or should I search for something else?
