Romance languages

Okay, I'm a fluent speaker of American English, and I'm planning on learning one of the so-called 'Romance' languages: the choice comes down to Spanish (probably most practical here), French (AAAAAAAA), and Italian (interested me ever since I read Catch-22).

So... which should I pick? And why?

Relevant to my interests. I've been studying Chinese for a bit, and I think i'm going to try to learn two at once. I know I'm going to fail miserably, but there are few things i've wanted more than to do this. I studied Latin a bit before going to college, and I've narrowed it down to either french, italian, or portugese. I don't really care about exoticism, I get more than enough of that through Mandarin.
