assistant: No problem. Any preference on times?

user: I would need to leave after 08:30.

assistant: TR1958 leaves at 8:40 - would you like tickets on that train?

user: Not yet.. just needed the ID. Also, looking for a place to dine in the center of town at a moderate price range.

assistant: I have many delicious options. How does Cotto sound? It's British food.

user: That works for me. Book it for 3 people at 21:00 on the same day.

assistant: Unfortunately, there is no availability for that time. Did you have a different time in mind?

user: Oh, bummer. How about 20:00?

assistant: That worked! Your reference number is WASWNFH0 .

user: Thank you. That is all.
