basically what u need to asks to her are just pretty simple questions, and try to avoid a Yes or No questions.
for instance, try to avoid this :
hi, are you hungry?
instead, try to says something like this :
actually i'm kind of hungry, by the way, what type of cuisine do u like?
by then, you could get to know her better in what kind of food does she likes, and you definitely wants to bring her to her favorite restaurant, though.
just something like that. hope it helps
