Hi, I'm looking for a train departing cambridge that leaves after 21:45.  Can you help me with a reservation?
Absolutely I can help with that. What day and to what destination are you traveling? 
I am traveling to london kings cross from cambridge. 
All trains leave at 23:00,what time would you like to arrive?
I do not have a specific arrival time.
Do you have a day you will be traveling?
I will be traveling on Saturday. 
the TR4898 leaves at 23:00. do you want a ticket?
Yes for five please. 
I made reservations for you your reference number is 0F1R2M73.
Thanks! I also need a guesthouse to stay in in the north.
There are 11 great guesthouses to choose from. Would you like free wifi or parking? Also what price range were you looking for?
It doesn't need to have free parking and price doesn't matter. I will take a suggestion as I'm not familiar with the area. 
I would recommend limehouse, a 4 star guesthouse located at 78-80 milton road. Would you like to book a room?
Yes I would like to book it for 5 people.
What day will you be checking in?
I actually don't need to book. I would just like the phone number, postcode, and price range. 
Limehouse is a moderately priced establishment. They're in postcode cb42je and their phone number is 01223300552. Is there anything else you want to know? Or anything else I can help with?
No that's everything I needed. Thank you!
Thank you, Have a great day.
