I'm looking for a moderately-priced place to eat.
Excellent, we have over 31 possible choices. Do you have a location or cuisine preference?
I am looking for a restaurant in the moderate price range in the centre of town. 
I have 21 restaurants that fit that requirement. What type of food are you looking for? Or would you like my recommendation?
Can you give me your recommendation please.
Restaurant One Seven serves British cuisine. Would you like me to book this for you?
Sure.  Can you book it for 2 people on Saturday at 11:30?
No, I'm sorry. I can't book that. Would you like to try another resturant?
Okay, how about another place in the same area and price range?
Yippee noodle bar was able to be booked, the reference number is 0Y6K4AF7.
Thanks so much.  That will be all I need today.  Have a nice day. Bye.
You are very welcome. Thank you for contact Cambridge TownInfo centre.  Good Bye.
