I need a place to dine, and I'd like to know what my options are in the way of moderately priced vietnamese cuisine.
I'm afraid there aren't any moderate Vietnamese restaurants. Would you like to try something else? 
I need something in the centre.
Okay, may I suggest british food?
What about a Gastropub?
The cow pizza kitchen and barn is in the centre of town on Corn Exchange Street.
That sounds great! Can you book a table on Sunday at 13:00 for 4 people, please?
Booking was successful. The table will be reserved for 15 minutes.
Reference number is : 5NITO74A.
Thanks. I also need train tickets from leicester to cambridge please
Sure, when will you be traveling?
It will be the same day as the booking and I need to arrive by 09:30
The TR7843 train arrives at cambridge at 8:54. Would you look to purchase tickets or get more information?
I would like to get the departure time and price first. 
It costs 30.24 Pounds, and leaves at 07:09. Can I help you with anything else?
Please book for me, thanks.
I have reserved 4 seats for you. Your reference number is 0ORGWOUA. 
Thank you. The restaurant and train were my needs today which were successfully met. Goodbye.
Thank you for calling Cambridge TownInfo Centre. Have a nice day. Good bye.
