I looking for an Italian restaurant that offers cheap food.
We've got about 5 to choose from. All of them are cheaper. Did you have a preference on the area? 
I would prefer one on the west area.
The La Margherita meets your criteria. Would you like to book a table?
Yes. Please book a table for 2 at 16:45 on friday and please give me the reference number.
Booking was successful. The table will be reserved for 15 minutes. Your reference number is OWGTR8M7. Will that be all?
No. I also need a train.
We have many trains I can book for you. Where are you departing from and going to? 
Departing Peterborough on Friday.  Heading to Cambridge.  I need to arrive by 09:45.  Do you have anything?
TR1662 departs at 05:19 and arrives at 06:09.  Will that work for you or would you like to try a later train?
That one is perfect. Thanks for your help. Good bye
I hope you enjoy the rest of your day too!
