I need a restaurant to dine at in Cambridge on my upcoming trip.
There are lots to choose from. What type of cuisine are you looking for?
I don't care. It needs to be on the south side and moderately priced. 
There are 2 options, pizza hut cherry hinton which serves italian and restaurant alimentum which serves modern european.  Can I book you for those?
Yes please.  I also need a hotel with at least 3 stars and free parking.
There is no hotel in south side,do you want me to try different area?
How about a Guesthouse in South side instead?
I'm sorry, there is no guest house that meets those criteria, either. Would you like to try a different rating, or a different area?
Sure, what about in the city centre?
I am not finding a guesthouse that meets your criteria.  Might a hotel work?
Is there not one in the same area as the restaurant?
There are 2, the Alexander Bed and Breakfast 4 star or the El Shaddai 0 star.  Both are in the cheap range and in the Centre. 
Okay. Can you try booking the El Shaddai for me fo Saturday for 2 people for 3 nights.
The booking was successful.  Your reference number is S8LZAB9P.  Is there anything else I can help with today?
No that would be everything, thank you!
Okay! Glad I could help. Enjoy your stay.
Thank you, I will.
Good bye, thank you.
