Task-oriented dialogue about: restaurant
train

Hi, can you give me information on trains? I need to leave from London Liverpool Street on Sunday, heading to Cambridge.
Yes, there are several leaving every 2 hours. The ride is 88 minutes long. Can I reserve a seat for you?
Can you reserve a seat for me on a train that arrives at Cambridge by 20:30?
I have one arriving at 19:07 would that be okay?
Yes. What is the price and train ID of that one?
The trainID is TR8260 and the price is 13.28 pounds. You said you wanted one seat reserved for this train?
Yes please. I am also looking for a restaurant in the west side of the city. I would like it to be an expensive restaurant.
I have several places, which type of food do you prefer?
I don't have a preference, but I'd like to book the same day for 2 people at 13:15. I also need the reference number.
What date would you like the reservation for?
On Sunday as well. May I also have the reference number please?
I reserved you a table at Graffiti. It's a great british restaurant in the west. Your reference number is SSXX4DVL . Is there anything else I can help with?
No thank you. Appreciate your help.
It was my pleasure. Have a wonderful evening. Goodbye.
