Hello, can you help me find a restaurant for my upcoming trip to Cambridge?
Absolutely! What type of food are you looking for?
I do not care. Just something in the south, moderate range in price. 
There are two options that match what you're looking for.  Pizza Hut Cherry Hinton and Restaurant Alimentum, which is modern European cuisine.  Does either sound good? 
i want to reserve a table at  Restaurant Alimentum
what day and how many people?
I would need it for 3 people for 17:30 on monday.
I have booked that for you and your reference number is 7HRLWXYB.  Is there anything else I can help with?
Thanks!  I need to travel to Kings Lynn from Cambridge for 3 people.  I need to travel Tuesday night, sometime after 20:00.  I need a reference number please.
I would suggest train TR8387 that leaves at 21:11 with arrival at 21:58.  Would you like me to book this one or do you need a different arrival time?
This is perfect. Please book for 3 people and give me the reference number.
Okay, I've booked 3 tickets for you on TR8387. It will cost 29.4 GBP. Your reference number is VF2TRXD0. Can I do anything else for you today?
No, that sounds about right. Thanks.
Enjoy your visit.
