I'm looking for a train to go to cambridge on tuesday. 
I am happy to help with that. Can you tell me where you would be leaving from? 
From London Kings Cross and I need it to leave after 18:15. 
I have 3 trains available. They leave at 19:17, 21:17 and 23:17. Would you prefer one of those? 
I'd like to book the 19:17 train for 8 please and need the reference number. 
I was successfully able to book the 19:17 train for 8 people.  The total fee is 188.8 GBP payable at the station.  Your reference number is L0TQ4FD6.
I will also need a place to dine. I'm thinking something cheap, after that. Maybe Portuguese food?
There are two cheap Portuguese restaurants located in the city, the Nandos and Nandos City Centre. Would you like to book a table with either of these?
I would like to dine in the centre area, so let's go with Nandos City Centre.
Sure.  How many seats will you need to reserve for the restaurant?
I will need it for the same amount of people.
What time would you like to make your reservation?
I would like to dine at 21:00.
Will you be dining on Tuesday as well?
Yes.  Please reserve a table for 8 on tuesday at 21:00.  Also can you give me the reference number?
OK, I've got you booked with reference number W5J24TC2, they'll hold your table for 15 minutes. Is there anything else I can help you with?
No thank you, that looks great. Have a good day.
Thank you, have a nice day, too.
Thanks for all the help. Goodbye. 
Goodbye and enjoy the restaurant and trip!
