I wanted help with finding a hotel in Cambridge today.
Sure, are you looking to stay on a certain part of town?
I don't have a preference.  But it does need to have 4 stars and include free parking. 
I have two hotels located in the west. One is cheap and one is expensive. One hotel is located in the centre and is expensive. Any preference?
 Can you tell me the area the cheap one is in and give me it's phone number? 
The cheap hotel is in the west.  The phone number is 01954714600. Can I help you with something else?
Yes, could you give me information on the cambridge corn exchange?
sure, what kind of information are you looking for?
I need the postcode please.

Have a great day, please let us know if you need any further assistance.
