I'm wanting a train that leaves on Friday and goes to Cambridge. 
Sure thing. What's your departure site and around what time would you like to leave?
I  want to leave after 16:45, depart from Birmingham New Street. 
The first train will leave at 17:40 and arrive at 20:23.  Does that sound good? 
This time works fine for me.
You train has been booked, and the reference number is ZETNNFN0. You will owe 75.09 GBP when you arrive. 
thanks, i'm also looking for some museums.
We have lots of wonderful museums.  Is there a particular area of the town you would like to find one in?
Yes, do you have any in the centre?
There's 11 museums in the centre is there a type of museum you'd like to visit? 
Anyone of those would work. Could you recommend something for me? I'll need the phone number, and address as well.
The broughton house gallery is very nice and the phone number is 01223314960 and the address is 98 king street.
What area is it in?
It is in the centre.
