I'm looking for a place to eat in the centre of town.
There are a lot of great places to eat in the Centre.  Do you have a type of food in mind?
Can you look up greek food please?
I do not have any Greek in the Centre. Do you have anything else in mind?
What about Mediterranean food?
There's 3 restaurants that match that criteria. What's your price range?
My price range is $50 to $75 dollars for 2 people. I would also like something that is walking distance from my hotel.
The gardenia seems to match your criteria, it is the cheap price range and in the centre, as is your hotel. Would you like a table booked? 
Yes, please. Can you make a reservation on Tuesday at 12:15? Table for 8.
Sure thing, I will work on getting this booked for you.
If Tuesday at 12:15 is not available, I would be willing to come earlier. 
Done! Your table will be reserved for 15 minutes. The reference number is YKX6V4O8. Can I help you with anything else?
Thanks. I also need train information for Wednesday with an arrival by 16:15.
That won't be a problem, can you tell me where you're leaving from and traveling to?
It should depart from Cambridge, destination is Kings Lynn.
TR 9468 arrives at 15:58, do you need more information or a booking?
I need the travel time, departure time and the price per ticket please.
That train departs at 15:11. The total travel time is 47 minutes. The cost of the ticket is 9.80 pounds. 
Thank you for the information. I appreciate it. Good bye.
You're welcome. Have a great day!
