Nope. You need to go through it like a proper date. That means:

-Paying attention to what she says (she'll probably do most of the talking)
-Paying for the date (Assume you will unless she offers to pitch in)
-Generally being a classy gentleman

Since it's Valentines day, you have better-than-average odds of scoring with her, or at least getting a second date. The point is, you don't want to act like you're trying to score with her.
