So I'm meeting a girl soon for a photography session (Told her I'm trying to get into photography and she agreed to model for me).

I figured it would be a good way to get in loads of kino. Anyway, I wanna have lunch with her.

Would it be better to say 'Hey do you wanna get lunch too' (or something like that) or 'Hey I'll buy you lunch/dinner too/I'll take you to lunch/dinner'?

So should it be question or statement of intent?
