U: Hi, I want to find a Chinese place to eat that's expensive.

S: There are 9 Chinese restaurants that match your criteria.  Is there a specific part of town you'd like to dine in?

U: I'd like to dine in the north if possible.

S: We have the Hakka and The Hotpot that match your search. Do you have a preference?

U: Let's go with Hakka, and make a booking for 7 people at 19:15 on Monday. And give me the reference number please.

S: Great the booking was successful, your reference number is 4DV3FA1B.

U: Does Hakka have great seating outside?
S: The Hakka has a nice outdoor dining area that is great on summer nights.  Is there anything else I can help you with today?
