I am looking for a restaurant in the centre of Cambridge that serves modern American food.
I was unable to find any restaurants matching that.
Then what about modern European?
I have 4 modern european restaurants in the centre. Do you have a preference on price range? 
No, just pick a popular one for me and book it for 1 person on Tuesday please. 
I  book you a table at riverside brasserie, I will send you the reference number.
Okay what is it?
I need to know the reservation time before I can book a table for you.
I would like the time to be at 14:00, if you cant get that time 13:00 will do. Can I have a reference number? I also need a train.
Your table has been booked at De Luca Cucina and Bar at 14:00. Your reference number is M81RFLPZ. 
Thank you. I need a train on Tuesday and I need it to arrive by 10:15.
There are several trains arriving in Cambridge before 10:15. Where are you traveling from?
I will be leaving from London Kings Cross.
I can help you with that but first how many tickets will you be needing?
One ticket is all I need. Thank you.
I booked a train leaving at 5:17. Your reference number is LG54YRTF.
Thank you for your help. That's everything I need for now. Goodbye.
You are most welcome, have a wonderful day!
