Task-oriented dialogue about: restaurant
train

I'm looking for a train that goes to Cambridge and arriving by 17:30.
I can assist you with that. Can you tell me where you would be departing from?
I'd like to depart from Stansted Airport on Saturday.
Sure, their is a train that leaves at 9:24 am. Does that work?
That is a little early. Is there one that arrives closer to 17:30.
Train TR7078 leaves at 16:24 and arrives by 16:52 with a travel time of 28 minutes. Would you like to book a seat?
Yes, 5 people, please. Reference number, please.
Your booking was successful and the reference number is 28UYG6JR . Is there anything else I can help you with?
Yes I am also looking for a restaurant in the centre and serves gastropub food. In the expensive price range please.
There are two restaurants that fit your criteria: Backstreet Bistro and The Slug and Lettuce. Does either of those appeal to you?
Let's go for the Slug and Lettuce just because the name is so intriguing. Book that for the same group of people, please, at 20:30, on the same day.
Okay great, I have you set and booked! Is that all?
I also need the reference number to the restuarant.
Booking was successful, table will be reserved for 15 mins. Reference number is : PE63CDWY . Is there anything else that I can do for you?
That will be all, thank you very much.
Thank you for contacting Cambridge TownInfo centre. I hope you have a pleasant trip! Goodbye!
