totally agree, one of my funnest dates was at Barcelona restaurant, I mentioned that i was going to go to the she wants revenge concert and we ended up leaving the restaurant to go to the concert instead... spur of the moment. Dont get me wrong, we ended up not even dating, but I had fun on that date. I'd say plan something fun and with not too much pressure, and if something comes up, go with it! Did you ask her what she wants??
