I am looking for information in Cambridge.
Are you looking for a certain type of attraction in cambridge?
I need a train going to Cambridge, departing from London Liverpool Street on Tuesday and would like to arrive by 12:45
The TR0088 departs at 9:39 and arrives at 11:07
I'd like to book for 6 people. 
Alright!  That's taken care of and your reference number is ZM4QYUPU.  Is there anything else I can help you with?  
Can you give me info on museums in town?
There are 23 musuems to choose from. 
Do you have a favorite?  Pick one for me please.  I need the postcode.
The museum of classical archaeology is in post code cb39da. Is there anything else that I can help you with??
I would also like information for a restaurant near the museum.
Okay. Would you like to narrow it down by food type or price range?
I actually don't need anymore information, thank you.
Very well, we are here if you changed your mind, have a great day.
