I need to take a train from cambridge to peterborough.
There are hundreds of options, I can narrow it down if you have a day, arrival time or departure time.  
I want to leave on Sunday and arrive at 16:00
I have plenty of options for you. Would you like to leave first thing in the morning or in the afternoon?
Earlier is better, since I need to be there by 16:00. 
TR3577 will arrive at 15:24 would that work for you?
Yes, how long is the travel and what is the price? 
The train ride is 50 minutes and will cost 13.20 pounds.  Would you like me to book that for you?
Not just yet. What time does that train leave Cambridge?
That train leaves Cambridge at 14:34.
Thank you, I appreciate it. I also need some help finding an African restaurant. 
There is a great African restaurant called Bedouin located in the Centre.  Price range is considered expensive but you get a great experience.  Would you like me to make reservations for you?
That would be great, thank you.
For how many people do you need your reservation for?
Actually I really do prefer something in the cheap price range. If there is no African restaurants, how about something Italian?
I recommend Ask. It is in the Center and is in the cheap price range. Can I get you a reservation there?
Actually, can you give me the postcode and phone number?  No booking necessary. 
Phone is 01223364917, post code cb21uf. Anything else you need?
No, that took care of all my needs. Thanks. Have a good one. Bye. 
You're welcome. You as well. Bye!
