We have many options for restaurants. What food type are you interested in eating today?
I would like Italian please. 
What area of town do you prefer?
It doesn't matter the part of town.

Actually, let's look for the train first, please. I'll be traveling from London Kings Cross to Cambridge on Tuesday and I'd like to arrive by 15:45.
The TR3456 from London Kings Cross on Tuesday departs at 13:17 and arrives at 14:08. Shall I book that for  you?
I don't need to book just yet.  But could you help me located a New Zealand restaurant?  
Unfortunately, we no longer have any new zealand restaurants in the city. Can I search for something else for you? 
I's sorry, but could you give me the actual train travel time between the two cities? I'm not good at math.
It takes 51minutes.
Thanks, could you also recommend could you help you help me find a place with japanese food? 
Wagamama is an expensive Japanese restaurant in the centre of town.
Okay please book a table for five people on tuesday at 18:00 and give me the reference number
I am unable to book it at this time.
Is there another Japanese restaurant in the center of town?
There are no other Japenese Restaurants in that area.
Could you try to book that again for 5 people at 18:00 on Tuesday?
Great news, the booking system is back up and I made your reservation! The Ref. # is ETUL1R4O. Anything else I can do?
Thank you very much. That is all for today.
