I've got a craving for some pasta. Can you find me a good Italian restaurant on the west side of the city?
I have two different ones that are great. One is cheaper and the other is moderately priced. Do you have a preference? 
Yes, definitely the cheap one.
That's the la margherita. Do you want me to book a reservation?
Yes, please! I'd like it for 15:15 on Thursday for 7 people.
Booked! Reference number: S22TYNUQ. The table is reserved for 15 minutes.
Great. I also need a train to stevenage.
Yes, there are 70 different options  Do you have a preference for day, and time?
Yes, I'd like to leave Cambridge on Friday, sometime after 12:30.
There is a train that leaves at 1:21pm and arrives at 2:10pm. Do you want me to book?
That won't be necessary.
Is there anything more I can help you with? 
No, that will be all thank you for your help.
Thank you so much for using our services! Goodbye.
