Hello, I'd like some information on a restaurant in the centre.
I have many types of restaurants in the center. What type of cuisine are you looking for?
I would like african food.
I highly recommend bedouin located at 100 Mill Road City Centre. It is in the expensive range. Would you like me to book you a table?
yes, please. for 7 people starting at 11:15 on sunday.
I was able to book the table for you, your reference number is 1CRCO6HT they will hold the table for 15 minutes. Do you need anymore assistance?
I would also like to find a train that would arrive at 19:45 and depart from Cambridge.
What is your destination and travel day? 
train should go to kings lynn and should leave on monday
Your best bet would be TR7803, leaving Cambridge at 18:11 and arriving King's Lynn at 18:58. Would you like a ticket?
Yes please that sounds good!
how many tickets should i book you for?
i apologize. i dont need to book tickets. but can i please get the travel time. 
The travel time is 47 minutes.
Thanks. That's really all I need. Goodbye.
