I am looking for a train from Stevenage to Cambridge.  Can you help me?
Of course! What day would you like to leave and what time would you like to arrive?
I am looking to arrive by 17:15 on tuesday.
I have found you a train that leaves at 15:54 and arrives by 16:43. Would you like this one?
Yes could you please book that for me for 8 people and provide a reference number for the booking.
Booking was successful, the total fee is 102.4 GBP payable at the station . Reference number is : AIM1QZ4C.
Thank you! I also am looking for a place to eat at in the west area. I would prefer a nice expensive one.
We have many fine restaurants in the west, but I recommend Sala Thong, which serves Thai food. Would you like to book a table?
Is there any place to eat that serves Indian?
Which area are you referring to?
I would like it to be in the West of town. 
Would you like me to reserve a table?
Yes please book it for 8 people on tuesday at 20:15
Which restaurant should I book? There are 5, in the west, that serve Indian food.
Can you suggest one that has an expensive price range, please?
Yes, I recommend Tandoori Palace. It meets your specifications. Would you like to book a table?
Yes, please book a table for 8 on Tuesday at 20:15. I'd also like the reference number, please?

Thank you so much. I think that will be it for today. You've been a great help. Goodbye.
I'm glad I could help. Have a wonderful trip and a wonderful day. Goodbye.
