Could you help me locate a restaurant in the east area of town?
Absolutely, there are quite a few restaurants. Can you help me by specifying what type of food you're looking for? 
I am interested in an expensive restaurant.  See what's available, and maybe I can choose from there.
I have five places, what type would you prefer?
Italian would be great.  I also need a train to Cambridge that arrives on Tuesday by 15:30.
There are no Italian places to dine, is there another food you would prefer before we book the train?
any expensive restaurant will suffice. Reserve it for 8 people at 18:30 on tuesday and I'll need the reservation number please.
Booking was successful. The table will be reserved for 15 minutes.
Reference number is : 51VEERAC.
I also need a train to Cambridge departing from Stevenage. 
What day would you like to travel on?
I'll be traveling Tuesday, and need it booked for 8. Could I also get the reference number for that as well?
The first train leaves Stevenage at 05:54 and every two hours thereafter until the last train at 23:54. What time would you like to leave or arrive?
Anytime would be great, I'd like to book it for the same number of people as my restaurant.
Ok, I've booked your party on TR0517, it leaves at 11:54.  Reference number is IAYFJ8SI.  Total is 102.4 GBP payable at the station.  Anything else I can do?
Reference number is IAYFJ8SI, that will be all
Great! Have a great day!
