user: Yes please book the train for 23:29.

assistant: How many tickets do you need?

user: I don't need a booking, but can you tell me the train ID, travel time, and arrival time of that train?

assistant: TR0123 is the train ID. It leaves at 23:29 and arrives at 24:07. Did you need any more information about the train?

user: No, but I need to find a restaurant. It should serve vietnamese food and it should be in the north.

assistant: Unfortunately, I'm not seeing any Vietnamese restaurants in the north. Would you like to try a different area or type of cuisine?

user: How about a Chinese restaurant. Ideally expensive.

assistant: Hakka and The Hotpot are both expensive Chinese restaurants on the north side of town. Would you like a table at one of these?

user: I'd like to reserve a table for 3 at The Hotpot for 10:00 Saturday. I'll need a reference number as well.

assistant: I've booked that for you. The reference number is ZAV4B1D8 . What else can I help you with?

user: That'll be everything. Thank you!
