Need a place to eat with moderate prices, but needs to have russian food.
Unfortunately, I wasn't able to find anything matching your request. Shall we look for a cheap restaurant instead? 
What about a Turkish restaurant instead? 
I have two in that range, in the centre. Is that area the right area for you?
Yes, that area's fine. Can you make a reservation for 6 people on Thursday at 5:30 pm with one of them?
Would that be at 5:30 pm (17:30)?
Yes, could I have the reference number as well please?
Sorry booking was unsuccessful. Can you try a different time or day?
Can you try 16:30?
I was able to make that reservation at 16:30 your reference number is AKF1B848.
I also need a train from Cambridge to London kings cross that leaves on Friday and arrives at 17:00.
The closest to that time is TR2420 which leaves Cambridge at 15:00 and arrives in London, Kings Cross at 15:51. Would that meet your needs?
Yes, it would. Can you book me 6 tickets for that for Friday please? 
Ok, I've booked 6 tickets, reference number FFVH42H7.  Your total is 141.6 GBP payable at the station.  Is there anything else I can help you with?
No, I think that is all for today. Thank you for all your help!
You're welcome. Let me know if you think of anything else you need.
