Is this creepy or thoughtful for first date?

So I am going to get lunch with a girl I know at college and I she already agreed to it for next week and I'm going to call her soon to set up the time and place. I don't know her well, only talked a couple times in a class we had so I don't want to come off as creepy but we're facebook friends and I just glanced at her facebook page including her interests and one of her likes was being a vegan (so she doesn't eat any animal products).

So my question is when I call her should I mention that I saw this and ask her if its true and if so then ask her where she prefers to eat. There is a place I found in the town we live in that has some vegan meals so I could suggest that if she doesn't name anywhere else. Also, should I follow suit and order something at the restaurant that is vegan (maybe same thing she gets) out of respect in case shes vegan for animal right purposes.

The other thing I could do is not mention it because maybe she didn't want me to know since she never told me and then if I don't say anything should I still order what she eats or would that give it away that I know?
