Where does the conversation probably take place?

M: Hello. I’d like this guidebook, please. How much is it?
W: All things are free here.
M: Oh, thanks. I’ll stay in the city for one week. Could you tell me what places I should visit?
W: Well, there are a lot. Are you interested in islands, such as Lantau?
M: Islands?
W: Yes. There are a lot of interesting things you can see—old villages and churches. And the scenery is beautiful. Take this booklet. It tells you more.
M: Thank you very much. That’s a great suggestion.
W: You are welcome.
