I need a place to eat that serves sea food. 
I have only one option that is in the expensive price range and in the center of town. It is called Loch Fyne. Would that interest you?
That works. Then I'd to book for seven people  at 11:00 on friday
Sounds Great! I will contact them about booking a reservation for seven people at 11:00 on Friday
Ok, could I get the reference number for that reservation please?
I'm very sorry there seems to be an error in our system.  There are no results for a seafood restaurant. Is there another type of cuisine you'd like?
Could you try the same requirement for Wednesday?
I was able to book you for a table for 7 on Wednesday at 11:00. The reference number is XBG9YHTB.  Is there anything else that I can help you with?
I also need a train to London Kings Cross, on Thursday. 
The TR8272 to London Kings Cross on Thursday leaves at 05:00 and arrives and 05:51.  The price is 23.60 pounds.  Is that a good train for you?
As long as it is departing from Cambridge and arriving before 14:00, I am good with that train.  I am needing to book for 7 people please.  
I have you booked for 7 on TR8272. Your total fee is 165.2, payable at the station and your reference number is TMUT96XE. Can I further assist you?
no that's all thanks!
You're very welcome! Have a great day!
