user: I'm looking for a restaurant in the center of town that serves european food.

assistant: There are several that suit your needs. Any preferences on price range?

user: Moderate price range, please.

assistant: The 4 matching restaurants are "hotel du vin and bistro," "galleria," "de luca cucina and bar," and "riverside brasserie."

user: Perfect! Can you please book a table for 3 people at Galleria for me on Monday at 16:30?

assistant: Booking was unsuccessful. Would you like to book another day or time slot? Or perhaps another of the restaurant choices for the same booking information?

user: Let's try for 15:30 and can I get a reference number please?

assistant: Ok. That worked. It is booked and your reference number is QBVP0ZV2 .

user: Great! I also need a guesthouse with free wifi. Something moderately priced, and I don't care about parking.

assistant: There are fourteen different options for your guesthouse. Is there a specific area you would like to be in? How about the star rating?

user: I don't have any preference. Could you just pick something and book 5 nights for 3 people beginning on Monday?

assistant: Let's go with acorn guest house. Unfortunately, that booking was unsuccessful. Want me to try something else?

user: Instead of 3 nights how about two nights?

assistant: There seems to be an error. Can you please restate your preferred number of nights, the day you'll arrive, and the number in your party?

user: Certainly. Two nights, three people, and I'll need that room starting Monday.

assistant: Great! Your booking was successful. The reference number is TWU9EM7U . Do you need help with anything else?

user: I don't. Thanks so much.

assistant: You're welcome! You have a great day!
