Hi! I'm looking for someplace to go in the centre.
Sure! Do you have any idea what you want to do?
It doesn't matter.  I just need a phone number and entrance fee.
I would recommend Great Saint Mary's Church.  The phone number is 01223350914, and the fee is 2 pounds. 
I also need a hotel with free wifi and e a 2 star 
Three places meet your needs, but two are in the north and one in the east, did you want me to go with those or run another search?
It should be a guesthouse and very expensive 
Nothing fits all of that criteria. Would you like me to find you hotels that are expensive, have more than 2 stars, and are guesthouses?
yeah, check hotels instead of guesthouses
Express by hoilday inn cambridge is a hotel in the easy, as 2 star rating and is expensive 
Awesome. Thanks. Can you book that for me?
Sure, what day do you want to begin your stay? How many days do you want to stay and how many people?
Three people starting on saturday for four nights please.  I also need a reference number.
Your reservation for 3 people at express by holiday inn cambridge this Saturday for 5 days 4 nights was successful. Your Reference number is : 3OTVBMSS.

That sounds great, thank you!
May I help you with anything else ?
Thank you for booking that hotel stay for me. That will be all for today.
Enjoy your stay, goodbye!
