"I don`t know what you should see," Valentine says. "All I can tell you is, this place we`ve come to, this is a city of desire.`You don`t look at this city and search within her to find what you want. You look at her and she takes on the shape of your true heart`s desire. When you look at her - that`s what you should see."

That is one concept of "city of desire" that I like :D
