When ordering, ask her what she likes. If she talks casually, then you should order more vegetarian dishes and less meat dishes, and it's best not to order brain flowers and so on.
Prepare hot drinks: corn juice and peanut butter are good (you can say "drink this, drink your more beautiful words" when ordering food)
Prepare a pair of chopsticks: serve her the first dish first, and then be diligent.
If she thinks you are a little embarrassed when picking up food, then you should be manly, eat it yourself and talk to her about some happy topics.
She agreed to your date, which shows that what she cares about is not eating, but enjoying the process, so good luck!
