Hi, price1993!
The simple dinner idea sounds great! I would just like to add that I hope that you're going to or if you've already asked her out, that you do so or have done so in person in some way, like face-to-face or at least on the telephone. Doing it like that would mean so much more than doing it by some other electronic communication.
I mention this because you've stated something about "when she answers me".
I wish for you only the best!
Thanks!
