Hey guys, I've been dating for about a month. I have a date scheduled for Saturday night, told her to come to my place for food and a movie. My idea is to surprise her and take her to Target (David Wygant idea) to pick up some ingredients and cook a couple of omeletes together (fast and easy) then walk around a bit before we relax and watch a movie inside with some wine.

Is it a good idea to emphasize and let her know beforehand that we are cooking instead of going out and eating? Also-picking up the ingredients together, good move or should I have everything ready by the time she gets to my house?
