I am looking for an expensive chinese restaurant to eat at.
Thank you, I will go to the peking restaurant at street city centre
Can you book me a table for 6 at 15:00 on sunday?
I'm sorry but it is not possible to book that time slot at that restaurant. May I try another time and/or day for you?
Can you see if there is a table for 6 at 14:00 on Sunday, then? 
Yes! I am glad to inform you I was able to book you at the Peking on Sunday at 14:00 for 6 people and your reservation number is TSREFNQW.
Thank you, can you please help me find a train on Sunday that will arrive in Cambridge on time for my reservation?
the TR7147 train departs sunday at 11:17 and arrives in cambridge at 12:08.
I actually need a train from Leicester to Cambridge on Sunday that arrives by 10:45.
There are several trains that meet your needs. TR0440 seems like the best option. It departs at 8:09 and arrives at 9:54. I can book this for you if you'd like, or there are three trains that run earlier in the day if you'd like information on those.
Yes, that would work. Can you go ahead and book me 6 tickets and provide me with the reference number, please?
Great you're all set reference number is 0FZ7ADG9
Awesome, you have been very helpful. That's all I need.
Wonderful. Have a very nice day.
