U: I'm hoping to book a train.

S: Where and when are you departing from?

U: I'm going to Ely from Cambridge on Sunday.  Thank you.

S: great, what is your preferred departure or arrival time?

U: I would like to arrive by 20:15.

S: The first train leaves at 5:50.

U: Do you have something that leaves later but still makes the arrival time?

S: There's a train that arrives at 20:07. If you don't want to cut it that close, there's an earlier train that arrives at 18:07.

U: Give me the arrival time and train ID of the earlier train. Also find me a cheap restaurant that serves north american food if available or Indian food.

S: The arrival time of the TR5389 is 18:07. There are four restaurants that meet your criteria. Would you like a recommendation?

U: Yes, any you choose will be fine. I'll need to book a table for the same day, at 15:30, and it will just be me.

S: I booked you a table at kohinoor! Here is your reference number ZTGXVBXU. Anything else I can do for you?

U: How is their service?
S: Kohinoor has some issues with their service. It is lackluster and slow according to some customers' reviews.
