I'm looking for a Lebanese restaurant that is expensive in price. 
I am very sorry there are no results for an expensive lebanese restaurant. Would you like to try for a different type of cuisine?
No I'd really like lebanese, is there one in the centre area?
I have the Ali Baba restaurant in the centre of town. They are moderately priced. Can I help you in reserving a table? 
Really? The Ali Baba is Lebanese?
Yes. The ali baba is lebanese. Would you like to book a table? 
Yes I would like to book a table for 7 people at 16:45 on thursday. 
The booking was unsuccessful, would you like to try another time? 
Is there an opening available at 15:45? I'll also need the reservation number if it's available.
Yes I was able to make that reservation at 15:45 your reference number XH49SBME.
Thanks, I also need a train from cambridge to peterborough afterwards
There are 16 trains leaving on Thursday after your dinner.  I would think 2 hours should be long enough?  So there is one at 18:06 I can recommend.
I'd like my train to arrive by 16:45, please.
I have train TR4814 that will be departing at 15:34 and will get you there by 16:24. Would that be something that interests you? 
Yes, that sounds like it will work for me.  Thank you for the information.  That should be all I need today. 
You are welcome. Thank you for contacting the Cambridge TownInfo centre. Good bye.
