Hey planning on coming out there. Please suggest a train that would arrive in cambridge at 12:30!
Where will you be leaving from?
I will be leaving from Broxbourne.
There is a 09:32 that would arrive by 10:32 for 17.90 pounds.  Does that sound good?  There are other options if you'd like to leave later.  
That works,  can you book seats for 4 on that and give me the reference number?
Booking was successful, the total fee is 71.59 GBP payable at the station .
Reference number is : BIBTGCNA. is there anything else i can help you with?
Do you have any suggestions for entertainment that are in town center?
We have lots of museums, architecture, and colleges. What would you be most interested in?
I would like a museum.
There are 11 in the centre is there a type of museum you'd like to visit? There are many art galleries and some science museums. 
My first choice, actually, is not a museum, but an entertainment attraction. What type of entertainment attractions are available?
We don't have any in centre.  Maybe  a different part of town?
You know, on second thought a museum may be fun. Could you search listings for a museum in the centre?
There are 11 museum in the city centre. Is there a particular type of museum you're interested in? Art? Science?
Art sounds good. Let's try that. 
Cambridge contemporary art is very edgy. The address is 6 trinity street, postcode cb21su, and it is free. Do you need more information?
No thank you that is all I needed today.
Enjoy your visit! Let us know if we can be of any more assistance.
