I'm looking for a museum.
Ok, there are 23 museums in Cambridge, was there an area you had in mind, or a type of museum?
How about a science museum?
How about the whipple museum of the history of science?
That sounds cool, I will just need the area it's in and the postcode. Oh, and how much is the cost to get in?
This museum is free to enter.  It is in the centre area, postcode cb23rh. Is there any more information that you need?
Yes I am looking for an expensive Korean restaurant in the city center.
I have found one Korean restaurant that matches your criteria, the restaurant is named little seoul. Would you like me to make reservations? 
Yes please. I need a table for 2 on Wednesday at 11:15.
Little Seoul does not have an empty table at 11:15. Would you like to try a different time, or a different day?
How about 10:15?
Your booking has been successful! The reference number is BV8FODGD. Can I help with anything else?
That will be all. Thank you.
You're welcome! Have a great day.
