What is the best way to attack a girl's heart?, Sb helps!!!

The internet cafe near my house just hired a girl to look after the daily business there. I find her so cute from the very first look. Moreover, my heart fall for her even more when I by chance heard that she is a student at Foreign Trade University. So she is a student just like me, and from a good university. I literally *like* her. But the problem is, I don't know how to make aquantance to her. I don't even know if she has had the 'someone special' or not (although I'm rather hopeful because I haven't seen her with some boy around, although sometimes her female friends come to the shop to chit chat with her).
Worse still, she doesn't seem to like chatting on the Internet (so I can find some way to get her Yahoo nick ;). Wow, it's so hard for me to start conversations with her, as there are always customers there. She looks really cute, the right kind of face that I like. Nah, I can't just let things as it is. Who knows how long she will stay with this job? If tomorrow she leaves, I'll be very sad!!!
Please sb gives me some advice, some consult. If you're a boy, what would you do to attack a girl's heart when she don't know you? And if you are a girl, what would attract your attention? How a strange boy would do to catch your eyes?
Help me quick plzzzzzz!!!!
(I post this problem in this forum because I know there are many girls here :) Hope you will give me some advice!)
