Yes, I need help finding a restaurant there in Cambridge.
There are quite a few restaurants here in the city! Did you have a particular type of food in mind, or a price range you'd like to stay within? 
I am actually looking for Efes Restaurant.  I would like to book a table for 7 people on Sunday at 19:30.  And please provide a reference number.
Ok your Booking was successful you Reference number is 3G02X88X.
Thanks. Can you check on trains for me?
As there are quite a few trains, what is your destination, departure, and arrival time needed? I will narrow them down for you.
I will be departing birmingham new street on Sunday. I want to arrive at cambridge by 14:15.
TR7468 would arrive Cambridge at 13:23. Would that work fine for you?
That would be great. I will need 7 tickets booked please.
Booking was successful, the total fee is 420.56 GBP payable at the station .
Reference number is : UI1LGPAY.
Thank you for your help. That's all I need. Have a nice day. 
Thank you and enjoy your stay in cambridge!
