Best opening against King's side castle

Theres someone I would like to beat at chess someday', and every single game she does the same opening, castling on the King's side like this 

I suppose what I'm wondering is whether knowing how she's going to play before hand is something I can take advantage of. Perhaps there is a counter-opening I can study in-deph?
