I'm thinking about visiting New York City, have you ever been?
As a bot, I don't get to travel, but I do know New York city has the highest population in the US. Is there anything else you'd like to know?
Oh wow I didnt know that, what else can you tell me?
Well, I know it also has the highest density of people in the US. What else would you like to know?
Any cool places to visit while I'm there?
One cool place might be the United Nations headquarters. Lots of international diplomacy goes on there.
Oh, wow! I didn't know regular people could visit the UN. Do you know what I should eat there?

Response: Oh, you should eat Brooklyn pizza when you are at New York City.
